Jessica Simpson Shakes It Onstage

Here are some Jessica Simpson photos from a recent performance –and from the looks of it, the singer is really getting into this song. Not only is Jessica singing, but she’s throwing down some wicked moves like she’s on one of those dance crew TV shows.

Jessica and little sister Ashlee Simpson are all about staying in shape it seems. And I think they are started to get a bit competitive about the whole thing, each one trying to out do the other. But which one is on the cover of Fitness magazine in a bikini? Uh oh!
