Is Kevin Federline a voice of reason?

Or putting him in the best position for custody of the kids? Word is that K-Fed has urged Britney Spears to enter rehab:

"Kevin has tried to convince Britney to check herself into rehab from every possible angle,” a source told the tab[Star Magazine]. “First he tried threatening to take away the kids, then he tried pleading with her to take care of herself.”
K-Fed even teamed up with his former nemesis, Spears' mother Lynne, in an effort to convince the “Toxic” singer to get help. “He’s afraid she’s going to hurt herself,” says the source.

It is beginning to look like Federline wasn't such a bad guy after all. I mean he spent a grip of Britney's money on sneakers, torn jeans, watches, and cigarettes but at least when he was with her, she kept her private parts covered up and stayed out of the clubs.
