Cameron Diaz and Alex Rodriguez left an exercise session together in Miami yesterday. Cameron flashed a wide smile and toted a coffee as the pair made their way to their car. The couple are hanging out in the city now that Cameron has wrapped her promotional duties for Bad Teacher and a stint in London on the set of her film Gambit. The pair, who both spent part of their childhoods around South Florida, like to spend much of their free time in Miami. Cameron sported a bikini on two of their boating excursions, but she and ARod are also getting domestic with trips to the grocery store and are reportedly in the process of building a Miami home. ARod is still recovering from his recent knee surgery, but Cameron will be back in action soon, heading to nearby Atlanta to shoot What to Expect When You're Expecting with Jennifer Lopez and Brooklyn Decker.
