Even though she couldn't explain why she was, Scarlett Johansson found herself laughing about the nude photos of her that leaked online on 'Late Show' (Weeknights, 11:35PM ET on CBS).

"I don't know why I'm laughing, it was terrible," she said.

"On the other hand, a way to look at it is a lovely thing for mankind," David Letterman said.

Johansson did have a big smile when Letterman mentioned that the man responsible for hacking her email account and stealing the pictures could be looking at 100 years or so behind bars.
