Drew Barrymore knows the power of a little sweat session, and that's exactly what the actress did in a dance class on Sunday. Drew shared a video to Instagram of herself busting a move with the group to David Banner's "Play," writing, "#sweatysundays Video by my girl @robinantin." Robin, a well-known choreographer and founder of The Pussycat Dolls, may have had some trouble while filming (you'll have to cock your head to the side for a bit), but Drew's impressive dance skills shine through. Just another reason to love her, as far as we're concerned.
