Cameron Diaz flashed a big smile last night when she arrived at LAX with her various Bottega Veneta bags. She left California a week ago in order to spend time with Alex Rogriguez in Florida, where she was spotted cheering him on during his Spring training with the Yankees in Tampa. They had weekends free for fun, though, and enjoyed a hilarious visit to Busch Gardens to ride the roller coasters. Cameron's back in Hollywood ready to focus on her upcoming Bad Teacher with her newly single costar Justin Timberlake, in addition to her next project filming Gambit with Oscar-winner Colin Firth. Cameron never suffers from a lack of roles, and BuzzSugar has another part in mind for her in Drew Barrymore's How to Be Single.
