Jessica Biel acts like a stripper and we act like we're not fully erect at work.

We've all seen Britney Spears's up-skirts. Cameron Diaz's modeling nudes, too. Now, at long last, we get to see another one of Justin Timberlake's chicks bare-ass. That's right, this weekend we finally get to watch Jessica Biel dancing topless in her new movie Powder Blue. She plays a single mom who strips to pay for her injured son's hospital bills, and hers is one of four interwoven stories about coping with loss seeing Jessica Biel naked.

We can't think of a better way for her to expose herself than playing a stripper (trust us, we thought long and hard on it). Biel is continuing a great tradition of actresses hitting the pole for roles—and we don't mean on the casting couch. In honor of her glorious reveal, Complex remembers the best starlet stripteases in movie history. Enjoy, and maybe wait a while before you stand up and walk around the office...
