Jessica Biel hot sexy david letterman nyc late showJessica Biel hopped the first flight out of LA last night after stunning in a girlie Giambattista Valli dress at the MTV Movie Awards and headed straight back to New York, where she's promoting her new film The A-Team on The Late Show With David Letterman.

Looking a little less feminine in long pants (which she paired with a flowy top and Louboutins), we're just impressed that she's smiling after that red eye!

Jessica, who presented the Best Kiss award to Robsten last night, recently dished on what constitutes a hot onscreen kiss for her.

"Probably cherry lip gloss is a good ingredient. And maybe an Altoid," Biel, who locks lips with Bradley Cooper in The A-Team, told MTV News.

Cherry lip gloss? How very Katy Perry of her!
