Rumours are swirling regarding Ben Affleck and JLo's romance
Since the rumours surrounding JLo and Ben's reunion have come to light, ARod has spoken out.
The former baseball star was pictured on Tuesday for the first time since JLo returned from Montana with Ben, and as he headed to a restaurant in Miami, he was asked by Page Six how he felt about their recent getaway.
"Go Yankees," he simply responded.
Alex famously played for the New York Yankees – a major rival to Ben’s beloved baseball team, the Boston Red Sox.

The Oscar winner is so devoted to the Red Sox that he once refused to wear a Yankees hat in a scene for Gone Girl, he later confirmed to the New York Times.
It comes after multiple sources revealed that Alex was "shocked" by Jennifer and Ben’s reunion and had hoped that he would "be able to make it work and reconnect" with his ex.
The mother-of-two is feeling inspired in many aspects of her life right now, and has been spending time in the studio, where she has promised a lot of fun in the next few months.
The star shared a picture of her on Instagram over the weekend showing her recording a song, and captioned it: "Sexy summer fun coming."
