Jennifer Aniston chatted on the phone post-workout in LA yesterday. She was dressed down in white fitness pants, tennis shoes, and a tight tank after also hitting the gym in casual gear last week. Her hard work paid off over the weekend when she made an appearance in a sexy dress at the MTV Movie Awards. Jennifer wore a sexy black leather look to accept her best onscreen dirtbag golden popcorn for Horrible Bosses at the show. She's since shared another funny role with fans, having participated in a spoof of The Bachelor. Jennifer wears a bear costume in Burning Love, a Yahoo! web series that debuted yesterday and also features Malin Akerman and Kristen Bell.
