At A Bar Mitzvah?! I think that’s the last place she wanted to have a wardrobe malfunction that exposed anywhere below the belly button! The Australian rap star was booked to perform at a Bar Mitzvah in Los Angeles this weekend and went through some pretty disturbing circumstances while performing her verse from Jennifer Lopez single “Booty” when the pants she wearing split while crouching down. Kids are actually heard shrieking in the background. LOL. Check out the footage after the jump!
