Demi Moore is a full-blown cougar, but her Twitter skills prove she's not that old. In terms of speed and frequency, her fingers are right up there with her husband's. At all times of the night, Mr. and Mrs. AplusK go at it, even Twitpic-ing under the covers. Interesting.

Naturally, we'd shy away from saggy boobies and we would've from Mrs. Kutcher's...if she had any. Despite being two years shy of 50, she's in amazing shape—not only does she look like a hot college student but she uses Twitpic like a bored sorority chick. And boy, does she know how to work her iPhone. See for yourself by clickin' the jump for Demi Moore's Hottest Twitpics.
