Jessica Biel stopped by the Letterman show last night. My God, how does a girl get her body this tight? I mean, seriously, I think the "quarter off the a$$" cliche totally works here. I think I could bounce off of it. Amazing. Of course, Justin Timberlake is hitting that. Expect to see them both courtside tonight when ABC presents The Lakers versus The Magic in Game one of the NBA Finals. Tons of more Jessica Biel pictures
