Rapper reportedly orders his ex-wife to clean up her act

Kevin Federline has urged Britney Spears to check into rehab.

He’s worried that the 25-year-old may hurt herself, it’s claimed.

According to US Star magazine, Brit’s estranged husband has been concerned about the effects of her excessive partying since they split up in November.

The mag states: ‘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.

‘He’s afraid she’s going to hurt herself and that Sean Preston and Jayden James will be raised by strangers. He told Britney to get help before it’s too late.’
