Britney Spears Back in Rehab; Spears' Dad Talks to FOX

Britney Spears checked into rehab Wednesday night for the third time in a week.

The pop star's manager Larry Rudolph confirmed to the Associated Press that Spears is at the Promises Malibu Alcohol and Drug Rehab Treatment Facility in Malibu, Calif.

Meanwhile, a spokesman for Kevin Federline's attorney told FOX News' Lisa Bernhard that the emergency hearing that Spears' soon-to-be ex-husband reportedly scheduled for Thursday was never set to take place.

Spears and Federline reportedly agreed Wednesday night that he would keep their two young sons while Spears was in rehabilitation, a program that takes between 30 and 45 days.

Earlier, Spears' father told FOX News that the troubled pop princess is "a sick little girl ... we're just trying to take care of her and other than that I have no comment."

Jamie Spears, speaking Thursday from his Louisiana home, added that the problems with Spears are "not about what other people think" and that he and Spears' mom are "concerned about our daughter."

Federline is also concerned for Spears, and wants her to get the help she is now seeking, sources told is reporting that Spears went to Federline’s house Wednesday night. Their two young sons were inside the house, and Federline would not let Spears inside. Spears then turned on the cameramen outside the home flailing her arms and hitting the cameras.

According to "Extra," Spears was picked up by her mother from Federline’s house at 9:30 p.m., where she had spent approximately 45 minutes. At 10:20 p.m., Lynne Spears was driving Spears and the two were seen arguing in the car.

Spears was wearing a white hooded sweatshirt over her head and was curled up in a ball in the front passenger seat. Spears and her mother arrived at the center at 10:33 p.m.

No Hearing

Michael Sands, a publicist for Federline's attorney, told FOX News they believed someone made up the news of the hearing and told Los Angeles Superior Court spokesman Allan Parachini about it.

Federline and his attorney Mark Vincent Kaplan say they never called for a hearing, and that no court papers for a hearing were ever filed.

Earlier Thursday, Jamie Spears told FOX News that Federline and his lawyer were not scheduled to appear Thursday at an emergency hearing in family law court, as Parachini had said. He also alluded to someone leaking misinformation.

Parachini later issued an update: "A lawyer has called the bailiff and indicated nothing is going to happen today," he said. He identified the lawyer as Kaplan.

Kaplan had contacted the court on Wednesday and asked for the appearance, according to the Associated Press.

"Kevin continues to be a very focused father with his children with hands-on management," said a statement from Kaplan, read by Sands.

Parachini had said it was not known what issue the 28-year-old aspiring rapper planned to raise, though the former couple are in a custody dispute over their two children.

"Our best information is he will be here; she won't," Parachini said. "But anything is possible."

Federline sought spousal support and sole custody of Jayden James, 5 months, and Sean Preston, 17 months, after Spears moved to end their two-year marriage in November, but a temporary order issued Feb. 1 granted joint custody through this month.

Since last week, Spears has checked into rehab three times and last Friday night, she shaved her head.

Rudolph issued a brief statement Tuesday confirming the 25-year-old pop star had entered rehab.

Spears left the Promises' Malibu facility on Wednesday, according to "The Insider" TV news magazine, less than a day after arriving.

Last week, she reportedly sought treatment at a center in the Caribbean but also checked out after a day.

The next day, she arrived at a San Fernando Valley hair salon, grabbed an electric razor and shaved her head bald. Afterward, she visited a tattoo parlor, where she had a pair of red-and-pink lips inked onto her wrist. Then she went out clubbing with friends before apparently checking into Promises.

In public again Wednesday, Spears attempted to keep a low profile, but TMZ posted video of her wearing a wig and leaving what it said was a lawyer's office.

Whether her recent behavior will damage her recording career is hard to say, said Vibe magazine music editor Jon Caramanica.

Spears, whose 1999 debut album "... Baby One More Time," sold more than 13 million copies, hasn't released a new album since 2003. Before her troubles began she had promised one this year, and Caramanica suggested that might be a good outlet to address what she's going through.

"I think the best thing she could do is make an album that engages with this subject matter in some way," he said. "Not only to have a good album but to have an album that's a declaration of emotional health."
