Jennifer Lopez & Alex Rodriguez Cozy Up For Yankees Game

Jennifer Lopez and Alex Rodriguez had quite the romantic weekend.

The cute couple cozied up to watch A-Rod‘s former team, the New York Yankees, take on the Baltimore Orioles.

“#saturdayvibes,” she captioned an Instagram photo of their feet, which you can see below,

“Boyfriend and girlfriend titles have been vocalized with each other. What was a hot, casual thing is turning into something more serious,” a source told E! News. “They can’t keep their hands off each other in public or amongst close friends. It got really hot and heavy and they want to see where this goes, but are hopeful it can lead into a future.”
