OK! Exclusive: Brit's Family Wants Her Back in Rehab

As Britney Spears' behavior continues to spiral out of control, and as it becomes more and more likely that her ex-husband Kevin Federline will maintain full custody of their two boys, her family, who attempted a drawn-out impromptu intervention at the troubled superstar's Malibu home in October, are banding together to ask Brit to give rehab another try.

"Brit’s parents, her brother Bryan, and her sister Jamie Lynn, were all hopeful she’d do what she needed to do to keep her children,” a family friend reveals in the new issue of OK! — on newsstands now. “But she seemed to just thumb her nose at everyone. So they are going to attempt another intervention and hopefully save her from herself.”

Almost a year ago, following Britney’s panty-less dive into hard-partying oblivion, her parents and then manager Larry Rudolph orchestrated a intervention, which ultimately led her to several rehab facilities in a matter of only a few weeks. Now the Spears family, including divorced parents Jamie and Lynne Spears, is hoping the holiday spirit will convince Britney to commit herself to long-term professional care so she can get well and have the opportunity to be a mother to Sean and Jayden.

“Although her mom and dad are divorced, they are banding together for the sake of their daughter and their grandsons,” the family friend tells OK!. “Her sister and brother have been meeting with their parents to figure out the best way to confront Britney. They know she needs a huge wake-up call if she is going to be successful in keeping her children and putting her life back on track.”
