Say it isn't so! Kevin Federline is going to join nasty Chad Michael Murray on the CW's One Tree Hill. He's coming on as a guest star, though we still don't know in what capacity or for how long. Britney Spears's ex, however, did make it clear that his shooting schedule would not interfere with his custody of boys Sean Preston and Jayden James. "We're told that he made it quite clear that if shooting interfered with seeing his kids, he would not be available," says TMZ.com.

Good thing K-Fed has someone smart telling him not to mess up the custody battle it actually looks like he'll win. But according to my coworker Marissa, who saw K-Fed at Tao in Las Vegas this weekend, the wannabe rapper didn't seem too concerned about scheduling conflicts as he drank Patron straight from the bottle!

Do you think Kev will make a good addition to One Tree Hill?
