Kevin Spacey does amazing impressions. And whoa, is that Alicia Keys? Film debut in "Smokin' Aces"? And did Dave just ask her out?

This has been a summary of tonight's "Late Show with David Letterman". Thank you.

EDIT: Later on, Conan was asking Kate Beckinsale out. I don't know if I got them confused, or if they're both just dirty old men.
