Jessica Alba @ Letterman

Jessica Alba arrives in black at NYC’s Ed Sullivan theater on Thursday for The Late Show with David Letterman. She changed into a gold sparkly dress for the show.

During Letterman, Alba talks about her time on stage with 50 Cent during one of his concerts in Amsterdam and answers some questions from the Cosmo quiz (she’s on the cover of the latest issue):

On if she’s ever fallen in love at first sight: “Yeah. It’s still trying to figure itself out (in reference to on-and-off-again lover Cash Warren).”

On if she’s ever stripped in real life: “Of course [I have but] I get nervous. I’ve been in monogamous relationships. You try to spice things up and I get nervous! I get nervous!”

On sex on the first date: “(unenthusiastically) Fine. Sometimes a good parking place is better [than sex on the first date].”
