When it comes to playing a dirtbag, actress Jennifer Aniston is the best!

The Horrible Bosses star took the stage at the 2012 MTV Movie Awards Sunday night to accept the award for Best On-Screen Dirtbag.

The actress, 43, who has been staying out of the spotlight lately, looked hot in a one-shoulder black leather dress. Aniston accepted the award from Ted stars Mila Kunis and Mark Wahlberg.

"I mean, do you know how long I have tried to have somebody let me unleash my onscreen dirtbag?" she asked. "And thank god this category just popped I would like to say thank you to the television show Friends for letting me unleash the inner sweetheart. And here's to [Horrible Bosses director] Seth Gordon for allowing me to be a dirtbag. Thanks, dirtbag."

Also nominated in the category: Bryce Dallas Howard (The Help), Colin Farrell (Horrible Bosses), Jon Hamm (Bridesmaids) and Oliver Cooper (Project X).
