Kevin Federline's acting debut on 'CSI'

LOS ANGELES, Oct. 13 (UPI) -- U.S. singer Kevin Federline appeared on CBS's "CSI: Crime Scene Investigation" in what was his acting debut.

TMZ reported on Federline's performance in which he played a common thug. Although only appearing in one scene, Federline reportedly played his part perfectly, with convincing delivery of his few lines, TMZ said.

"This little piggy went wee, wee, wee all the way home," was one of Federline's sneering lines. TMZ described his delivery as Spacey-esque.

Federline, who is married to Britney Spears, did admit to sources that his lines were "catered" to him, TMZ said.
