Gavin Rossdale goes Goth for 'Criminal Minds'

Bush frontman Gavin Rossdale will rock it out on "Criminal Minds" this season.

CBS announced Wednesday that Rossdale will guest star on an episode of the crime drama this fall, playing a Goth rock star who gets a bit too consumed by the scary alter-ego he plays on stage.

The Behavioral Analysis Unit, however, suspects that this alter-go might actually be a serial killer.

Rossdale, who's married to Gwen Stefani, has exercised his acting chops before in films such as "Constantine," "Little Black Book," "Game of their Lives" and "How to Rob a Bank."  

The new season of "Criminal Minds" premieres on Wednesday, Sept. 23 at 9 p.m. ET/PT.
