Actor-musician Rick Springfield will flaunt his backside during his guest starring stint on Showtime’s Californication, according to the Associated Press. EW’s Michael Ausiello broke the news of his casting back in April and revealed that Springfield would be doing “tasteful nudity.” “It’s not full-frontal, but it’s pretty much full on,” Springfield told the AP. “As long as it’s for the part, I’m cool with it. And it’s funny. It’s not done to be particularly sexy.” The “Jessie’s Girl” singer plays a “twisted, warped version” of himself for four episodes, starting this Sunday, and will disrobe by the end of the season.
