Britney Spears Sexes Up Jimmy Kimmel (PHOTOS)
To kick off the week, she rocked a sold-out crowd for her Good Morning America show (see pics) on Sunday (which aired Tuesday). Then last night she showed she's not taking herself too seriously with a gross-out porta potty skit on Jimmy Kimmel Live
While her comedic timing is on point, the Brit we love best serves it on stage -- which is exactly what she did! Natch, girlfriend had to change things up with a whole new wardrobe than previously seen on GMA.
