Mr. Ashlee Simpson, aka Fall Out Boy bass player Pete Wentz, is making the TV rounds these days. Besides his new gig hosting FNMTV on MTV, OK! Magazine reports the spiky-haired king of guyliner will be playing himself on an upcoming episode of Showtime's Californication.

No word on the plot line, or how much screen time the rocker will have, but we know Ashlee will be watching with bells on!
