Rihanna has already finished her new video for Rockstar 101 even though she just announced last week that it was going to be her next single. The video also features Travis Barker, who is teaching her how to play the drums for her upcoming "Last Girl On Earth" tour. After seeing her performance on American Idol last week I'm very excited to see this video now! You can just tell it's going to be good.

Ps. Speaking of the tour, Nicki Minaj was supposed to join her but she quickly backed out; with alot of people saying Rihanna kicked her out because she didn't want to be upstaged. I don't know it sounds ridiculous to me because really who can upstage Rihanna right now?
