Jimmy Kimmel's Workout Tape: Scarlett Johansson, Jessica Alba, Sofia Vergara, Lindsay Lohan

So this is how Hollywood actresses stay fit. Or at least stay humble.

Jimmy Kimmel brought together some of Hollywood's biggest leading ladies in this spoof workout tape for the Hottie Body Hump Club. Jessica Alba, Scarlett Johansson, Jessica Biel, Sofia Vergara, Eva Longoria, Emily Blunt and, none other than Lindsay Lohan get in on the act of fawning over Jimmy and thrusting like there's no tomorrow.

Lohan, of course, got the wackiest part, working with a CGI lion and then poking fun at her legal problems.
