Jennifer Aniston 's Mexican vacation is still going strong, and yesterday she slipped into a purple bikini. Jennifer continued to relax in the pool with shirtless  Justin Theroux, with whom she shared a few steamy kisses on Tuesday. The couple arrived in Mexico earlier this week to vacation with a few friends, including her Horrible Bosses costar Jason Bateman  and his wife, Amanda Anka. The foursome shared a laugh while soaking in the sun at the pool together yesterday. Jen's been recently dealing with her business side, too — after wrapping up a month of filming Squirrels to the Nuts in NYC , Jen was busy promoting We're the Millers with multiple TV appearances and an awkward interview with Chris Stark , a British comedian. Jennifer only returned to LA briefly before heading out of the country.
