Ethan Hawke – already the father of two children with his ex-wife Uma Thurman – is about to become a father again, this time with Ryan Shawhughes, described as the former nanny to his children.

“I can confirm and they are thrilled,” says Hawke’s rep Mara Buxbaum. “No further details will be made available.”

Speaking in December 2006 about the joys of fatherhood, the 37-year-old actor-author said, that his two children with Thurman – daughter Maya, now 9, and son Levon, 5 – provide “the greatest pleasure in my life. It’s the only role that, if I fail, I will consider my life a failure.”

As for sharing parental duties with fellow New York resident Thurman (they split in 2004, after seven years of marriage), and yet managing to keep their distance from one another, Hawke also said, “We live down the street from each other. If we lived down the street from each other in Minneapolis, I’d have to watch every car go in and out of the driveway. I’d know how late she stayed out.”

Given how things turned out, he said with relief, “I don’t have to know any of that stuff.”

In Touch was first to report the story.

American Pie star Jason Biggs is engaged to his girlfriend, actress Jenny Mollen, a rep for the actor confirms.

The couple looked cozy at the premiere of 29-year-old Biggs’s new comedy Over Her Dead Body Tuesday night, and Mollen, 28, was sporting a impressive ring.

The pair met on the 2007 set of My Best Friend’s Girl, which is set for release this fall.

From Puff Daddy to P. Diddy then to simply Diddy, it seems like with every season comes a new nickname for music and fashion mogul Sean “Diddy” Combs – but he says new rumors about his name changing are false.

Combs told Ryan Seacrest on the KIIS-FM radio show Wednesday that contrary to reports, he will not be changing his name to Sean John.

“I have been there done that,” he told Seacrest. “Too much of the name changing thing is when somebody is going crazy. I’m not going crazy. I’m very sane and I’m not changing my name.”

Asked where the rumor came from, Combs revealed the possible source as a fashion show for his clothing line. “I think I made a comment during the Sean John fashion show about it…and I think it got turned into I’m changing my name.”

Jessica Simpson and Tony Romo had a low-key (but big-haired) night out on the town in West Hollywood on Monday.

The singer and the football star, accompanied by four other friends, hit the Key Club for the hard-rocking Metal Skool Night. The pair were seated in the VIP section, protected by a bodyguard.

But they were sweetly affectionate, according to an observer, who said Romo wrapped his arm around Simpson and rested his head on her shoulder. She, in turn, playfully rubbed her forehead on his cheek. (Awwww.) At one point, the pair also hopped onstage to rock out with the band.

Britney Spears is having some family bonding time with her mom – but the pair have been seen arguing, according to sources.

Lynne Spears, who arrived in Los Angeles Monday, accompanied her 26-year-old daughter and pal Sam Lutfi to a Mercedes Benz dealership in Beverly Hills Tuesday morning – but it was not exactly a happy family outing.

“Lynne and Britney were arguing in the car the whole time. They’re both upset and arguing, not having a good time at all,” an onlooker says.

After 15 minutes at the dealership, Britney drove a black Escalade off the lot. “After she came out, she pulled over to the side of the road to argue with her mom more,” adds the onlooker.

The previous night, Lynne had visited her daughter’s home, but then was left to pace around the house after Britney left the house to meet Adnan Ghalib.

“Lynne, at one point said, ‘I just want to give her a hug. I’m very worried,” says a source. “Lynne was so nervous and worried, she just kept asking how they could get her daughter back home.”

When the pop star did return home, Lynne, Britney and several friends including, Alli Sims and Sam Lutfi, had a “family bonding session over a lot of things,” says the source.

But the family time does not seem to have changed Britney’s behavior. On Tuesday afternoon, she and Lutfi visited a nearby J. Crew, where an onlooker described her as “totally out of it.”

“She was talking in a slight accent. It was a little of a British accent,” says the eyewitness. “She kept to herself, quiet, she just wanted to go. She really wanted some Bubblelicious gum and she kept asking Sam for it and got frustrated when he didn’t have any. Her mood lifted when she found some in her bag.”

Gwen Stefani and her rock star husband Gavin Rossdale are expecting their second child, Rossdale’s father confirms.

“They and the whole family are delighted,” Douglas Rossdale says.

Reps for Stefani were not immediately available for comment.

According to Britain’s The Sun, the singer is 13 weeks pregnant. She has long said she’s wanted another child.

Stefani, 38, and British-born Rossdale, 40, wed in London in September 2002 and have one of the coolest kids in showbiz: Kingston Rossdale, who turns 2 on May 26.

Stefani has described Kingston as a “chilled-out little guy. He’s just like another person, except that he’s super-cute and super-entertaining.”

When it comes to his son, Rossdale recently said, “Finally, I got something right.”

Grandpa Rossdale sings Kingston’s praises too. “He is a great lad,” says the senior Rossdale. “And we are very much looking forward to another grandchild.”

Actress Sean Young entered rehab for treatment related to alcoholism Monday.

Young, 48, voluntarily admitted herself, according to a statement released by her rep, which read: “It is understood that Young has struggled against the disease for many years.”

On Saturday, Young caused a scene at the Directors Guild of America Awards in Los Angeles when she heckled The Diving Bell and the Butterfly director Julian Schnabel during his acceptance speech. She was promptly removed from the venue, according to a Variety report.

Headline-grabbing antics aren’t anything new for Young. In September, an Entertainment Weekly piece revisited her attempt to crash the 2006 Vanity Fair Oscar party, which also got her escorted out.

Also mentioned are the harassment of former costar James Woods and her attempt to get a role in Batman Returns by “[storming] the studio lot wearing a homemade Catwoman suit.”

She did not get the part. Young’s best-known movie is 1987’s No Way Out, starring Kevin Costner.

Just hours after Britney Spears’s camp announced that she was seeking psychological treatment, the pop star appeared back in the midst of actions that seemed anything but therapeutic.

Around 9 p.m. Monday, Spears’s father Jamie and her mother Lynne – who earlier visited Britney’s kids Preston, 2, and Jayden, 1 at Kevin Federline’s house in Tarzana – arrived at their daughter’s home.

Whatever occurred at the family reunion didn’t last long, as Spears, clutching a bag, bolted from the mansion, hopped into a car with her paparazzi pal Adnan Ghalib and sped off, says a source.

Their getaway hit a speed bump, however, when their car got a flat tire and forced them into a Chevron station for air. They then returned to Britney’s house and to mother Lynne, leaving Ghalib to depart soon after.

About 90 minutes later, around 1:30 a.m., mother and daughter left the house together themselves, headed to a Longs Drugstore in Studio City.

The Long Night Begins
The action-packed evening actually got underway much earlier Monday evening, when Spears and her confidante Sam Lutfi went for a short drive around Beverly Hills.

When they returned to her Summit home at around 6 p.m., the visibly distraught singer – who appeared to be arguing with Lutfi – jumped out of the white Mercedes near the gated community’s guardhouse.

Spears – wearing brown high heels, cutoff shorts and a plaid fedora as she clutched her Yorkie puppy London – wandered around in tears and, at one point, sat down on the curb. “She looked completely lost,” says an on-scene source.

Only Spears seemed to downplay the incident, saying, “I’m fine. I’m … having a nice time with my dog.”

The singer ended up hopping into a car with photographer Filipe Teixeira, who gave her a lift to a Ralph’s supermarket in Studio City before he brought her home – and she invited him and another photographer inside. Ghalib, who’d been noticeably absent from Spears’s side in recent days, showed up about half an hour later.

Police Summoned
Later on, police cars pulled up to the house in response to a call from security at Spears’s gated community.

“Spears drove through the gates and paparazzi followed her car on foot,” said LAPD Officer Mike Lopez. “By the time officers arrived, the paparazzi were off the property, but officers handed out citations for those who were illegally parked.”

Filming of Michelle Williams’s next movie, Blue Valentine, has been put on hold while the actress copes with the death of Heath Ledger, a source says.

“We will hold off until she is ready,” says a source connected with the film. “The production is in the process of sorting it out in respect to her.”

The movie – a relationship drama centered around a young couple struggling with their marriage – also stars Ryan Gosling, who Williams was rumored to be dating after they were spotted strolling together in New York before the holidays.

Production on the film was set to start on February 25, but has been moved back to an indefinite date.

“We’re hoping she will still come back and do the film and are happy to wait,” the source says. “The film is tailor made for those two so of course we would want to wait. You can’t get much better than them.”

Williams had just finished shooting her last scene in the film “Mammuth” in Sweden when she received the news of Ledger’s death.

Britney Spears is allowed to speak with her children on the telephone but still may not see them, according to court documents released Monday.

“(Spears) is to have telephonic contact with the minor children,” Commissioner Scott Gordon ruled at last week’s hearing. “All prior orders remain in full force and effect.”

The pop singer, 26, has been forbidden to see her sons Preston, 2, and Jayden, 1, for more than three weeks, following her Jan. 3 custody standoff, which ended with her brief hospitalization.

Despite two attempts by her lawyers to regain her visitation rights, Spears cannot see her kids indefinitely, the judge has ruled.

Earlier Monday, Barbara Walters reported that Spears is seeking help for mental issues, according to confidante Sam Lutfi.
