Amy Poehler's in the house with a classic satin number that says, "I have my own NBC show and you don't." But for one of TV's funniest ladies, she could have taken her outfit as far as she goes with her humor.

Most of the time, lingerie-meets-evening-attire is a trashy affair. But at The Hangover's premiere, the smoldering Heather Graham is a welcome break from the everyday.

Katy Perry sports her signature, pinup style at the Glamour Women of the Year Awards in London, but the extra fabric in front ruins the dress' lines. And just in case you forgot she "Kissed a Girl," the pop star has an extra pair of lips in tow.
