Video Shows JLO Rehearsing with Ex As A-Rod Looks On

Alex Rodriguez appeared to keep his cool as his girlfriend Jennifer Lopez shared the stage with her ex Marc Anthony at a theater in Dominican Republic.

Footage obtained by TMZ showed the former couple rehearsing at an historical amphitheater Saturday as Rodriguez watched from the VIP section.

Rumors swirled that JLO and Anthony rekindled their romance, but it appears A-Rod is still in the picture and keeping close to Lopez.

The couple kept quiet about their romance for some time until Rodriguez opened up on The View in late March.

“We’re having a great time,” A-Rod said. “She’s an amazing, amazing girl. One of the smartest human beings I’ve ever met and also an incredible mother.”
