Cameron Diaz and Alex Rodriguez’s on-again, off-again relationship is back on. We spotted the couple in Cabo San Lucas with A-Rod’s two daughters Natasha and Ella. Cameron splashed around in the pool with the girls for hours while the New York Yankees slugger enjoyed looking on from the side.

The couple have been dating since this summer. They broke up in October and now they’re back on again. A source close to Alex said that this is a pattern for them. They break up and get back together all the time. Nothing like a solid foundation to build the relationship on.
