VIDEO: Blake Lively Swipes Jimmy Fallon's Butt

Blake Lively paid a visit to Late Night with Jimmy Fallon yesterday, and made sure to address all the rumors circulating about her. As it turns out, most of them are true! Blake tends to break out into Riverdance jigs and can also recite the lines to Waiting for Guffman by heart. She also enjoys "credit card swiping" her friends, a pastime she explains and also performs on host Jimmy Fallon. Looks like he is approved!
