Britney Spears’s children were safely with Kevin Federline when the pop singer was taken to the hospital Thursday morning for the second time for a psychological evaluation, a source says.

Federline, 29, was not directly involved in these latest events, “but he was aware of what was happening,” says a Federline friend.

“Kevin legitimately wants Britney to get better. He wants her to be in their sons’ lives. He wants them to have a loving relationship. He wants her to get healthy so she can be the mother they need and deserve,” says a Federline friend.

This is the second trip to a hospital this month for Spears. On Jan. 4, she was forced into the hospital following a tense custody standoff involving sons Preston, 2, and Jayden, 1. A court commissioner has since stripped Spears of visitation privileges.

Another source says that getting medical help again for Spears, 26, “has been planned for a long time. Her family is behind this.”

Former E.R. star Julianna Margulies and her lawyer husband Keith Lieberthal welcomed a baby boy, according to the couple’s family.

“Obviously I’m utterly delighted to be a grandfather,” said Keith’s father, Dr. Kenneth Lieberthal, when reached. “I have to say, he is cuter than any other baby I’ve seen.”

Margulies’s mother, Francesca, was coy when asked about her daughter’s new son, saying, “I better not open my mouth. I don’t want to get in trouble with my daughter.”

However, on her outgoing voicemail message, amid background violin music, Francesca announces, “A beautiful baby boy has been born to us. All is well. His name is Kieran Lindsay Lieberthal. Is that poetry? Do a little dance. Love this day! All is well. God bless! Can’t wait to hear from you.”

Margulies, 41, and Lieberthal, 35, were married in November in Lennox, Mass. She had said earlier she was “doing great” with her pregnancy. This is the couple’s first child.

Mary Lynn Rajskub, who plays computer whiz Chloe O’Brian on Fox’s 24, is pregnant, she says.

Rajskub, 36, and her live-in boyfriend Matthew Rolph, 27, a personal trainer, are expecting their first child at the end of the summer.

“With the strike going on, I had to keep busy!” Rajskub jokes. “We are thrilled and couldn’t be more excited.”

Rajskub recently attended the Sundance Film Festival promoting Sunshine Cleaning, in which she costars opposite Amy Adams and Emily Blunt. On Friday, Rajskub will make an appearance walking in the Red Dress Fashion Show to benefit The Heart Truth in New York.

Katherine Heigl has been married all of a month, and she’s already noticed a few differences between her husband and herself.

The 27 Dresses star tells Oprah Winfrey that husband Josh Kelley is “charming beyond belief. He is sexy and talented, … so kind, and he’s so compassionate.”

And how does she rate herself as a wife?

“I’m not always so nice,” she says. “I have my moments.”

The interview airs Friday on The Oprah Winfrey Show.

Britney Spears was hospitalized at UCLA Medical Center for a psychiatric hold early Thursday morning, after being transported by ambulance from her Studio City home around 1 a.m.

An LAPD source says: “Spears was escorted by police and is on her way to get help.”

The singer, 26, was transported to UCLA for treatment and evaluation during a 72-hour emergency hold, known as a 5150.

“She went willingly. It was like something in her heart was telling her she should go. She knew something was wrong,” confidant Sam Lutfi said.

Police or a mental health professional can request one if a person is deemed to be a danger to herself or others. (Spears was held at Cedars-Sinai Medical Center on such an order earlier this month, following her Jan. 3 custody standoff with police.)

Spears’s mother, Lynne – who’s in the midst of a tense reunion with her daughter – friend Alli Sims and Lutfi were all inside the gated mansion when police and the fire department arrived.

What brought on the hospitalization? “She was driving around her neighborhood like a mad-woman,” says a Spears family source. “Britney has been prescribed medication which she refuses to take. This is just another sad, sad evening.”

Lutfi and Spears’s father, Jamie, arrived at the hospital shortly after the singer. Her mother was later spotted leaving the Summit home with Spears’s photographer beau, Adnan Ghalib, in the backseat.

Earlier in the night, Internet rumors claimed that the singer had attempted suicide, but Lutfi and Sims both denied those claims.

Since the January standoff, Spears has been stripped of visitation rights for her two sons Preston, 2, and Jayden, 1. Two sources have said she suffers from a psychological disease, with one source saying, “there is no question she is bipolar… she’s had manic episodes for years.”

As last night’s incident unfolded, a Spears source said simply, “Pray, please.”
