K-Fed's Says Ex Was a "Lying Bitch"

K-Fed took another stab at "acting" last night -- remember his horrendous "CSI" appearance?! This time he played a wannabe rocker on "One Tree Hill." What's that smell? Emmy!

He's no Chad Michael Murray, but at least he's better than Britney was in "Crossroads." But not much.
