Here's To The Night(life)!

K-Fed does know how to party! Here's a pic of him at the Venetian's Tao Nightclub in Las Vegas last year. And guess where he was this weekend? At the very same club, throwing a few back, according to People.com.

The report says Federline hit the club on Friday night with a party of 25(!) and never seemed to have time to pour himself a drink... into a glass, that is. People.com quote an onlooker as saying, "He was drinking straight from the vodka and Jagermeister bottles," before finally leaving Tao at 4 a.m. Sounds like he had a good time - always nice to take a break from your troubles!

But Kev's lawyers did no such thing. Continuing their crusade, K-Fed's lawyer Mark Vincent Kaplan confirms that staff members at Promises - the treatment center Brit attended - were served with a subpoena Saturday morning. It never ends, does it?
