Nicole Returns From Mexico and Hits the Gym in Leather

Nicole Richie layered a black, studded leather jacket over her gym clothes.

Nicole Richie was back at the gym in LA yesterday following a weekend trip to Mexico with friends. The result of her efforts in the gym were on display at her Cabo resort when Nicole was spotted lounging poolside in a sexy black bikini in the company of her good friend Samantha Ronson. The pair sipped drinks and grabbed lunch with pals Jessica and Ashlee Simpson who were also vacationing in Cabo. Nicole and Jessica's friendship goes way back, and the successful pair recently had the opportunity to work together professionally on the upcoming fashion competition, Fashion Star.
