Nikki Sixx Turns Down Rhianna

Nikki Sixx turned down an offer to appear in Rhianna's new video. Of course Sixx took to Twitter to let the world know he let he down easy, he wrote:

“Rihanna just asked me to be in her video for “Rockstar". I respectfully said no. What do you guys think?”

Rihanna moved right along and recruited Travis Barker. Considering her latest hook up with Lady Gaga it appears that Rhianna is looking for some street cred.
