Kevin Federline tries to get Britney Spears into rehab!

When Britney Spears was still with Kevin Federline, he was portrayed as the party guy, leaving his kids at home with her to hit the Strip in Las Vegas. Ever since Spears filed for divorce, however, she has been the one out at the clubs every night and stumbling home every morning. Sources says Kevin is frustrated with Britney's behavior and he has suggested that she go to rehab, for the welfare of their children together, Sean Preston and Jayden James.

An insider told Star magazine that Federline even sought the help of his former foe, Spears's mother, Lynne to help with the situation. The snitch says, "He's afraid she's going to hurt herself…Kevin has tried to convince Britney to check herself into rehab from every possible angle. First he tried threatening to take away the kids, then he tried pleading with her to take care of herself."

Like the public, Kevin is concerned with the fact that Britney seems to spend all of her time going out rather than spending it with Sean and Jayden. The source told Star, "[The kids are] being raised by strangers. [Kevin] told Britney to get help before it's too late."
