Kevin Federline is carousing it up in Las Vegas this weekend while his ex-wife Britney takes care of the kids. Just cause he’s in Vegas doesn’t mean his lawyers aren’t working. Kevin’s lawyers did it again. This time, they served Promises Rehab Facility where Britney spent a month ‘seeking’ help. "Kevin and his attorneys Mark Vincent Kaplan and James Simon are on a mission," a source told People Magazine. "They are pursuing all relevant evidence from every potential source and every available witness."
Basically they wanna know if Britney bull shited her way through rehab or if she actually proactively seeking help. Pepperdine University Law Professor Steven M. Cron says, "Strategically I don't think they are concerned with the treatment, but how she responded to that treatment," says Cron. "Specifically, if she participated as she was supposed to. Did she have a positive attitude, did she complete it successfully. Or was she a screw up?"
