Though she usually keeps a relatively lower online profile, Britney Spears popped up in a couple of unexpected places in March. In a viral video that debuted on the Jimmy Kimmel show, Britney appears in what looks like an outtake from the "Jackass 3D" movie. She seems quite enthusiastic about being shot hundreds of feet in the air in a full porta-potty. Of course, this didn't really happen, but at least they got her on camera saying that she's not afraid of "poopy." Britney was also abuzz on the web due to a couple of surprise performances she gave in Las Vegas and San Francisco.
