Matthew McConaughey and Camila Alves touched down at LAX yesterday. They're back in LA after taking a trip to Spain with Bono and his wife, Ali Hewson. Pregnant Camila wore a bikini to swim in the ocean while Matthew showed off his shirtless physique. He looked slim since he's been losing weight for his upcoming role in The Dallas Buyer's Club. Matthew's just one of the hot guys in the running for our 2012 Shirtless Bracket, so make sure to vote for him and your other favorites! Matthew will soon get started on his new role, after promoting multiple projects already this Summer. He traveled around the world for Magic Mike, and most recently talked up Killer Joe in NYC.
