The lovebirds spent the weekend together soaking up the sun, and it appears the World of Dance star's 9-year-old twins, Emme and Maximilian, may have fallen just as hard for the former MLB pro.

Lopez took to Instagram on Wednesday, sharing a series of sweet pics of her kids hanging out by the pool with her new beau. In one of the photos, Max can be seen lying on top of Rodriguez's stomach as Emme adorably looks on with a smile.
"SWIPE FOR MORE PICS," Lopez, 47, captioned it. "#aboutlastweekend #summertime ☀."
The post comes just a few days after the pair was spotted out and about in East Hampton, New York, strolling hand-in-hand.
ET chatted with Rodriquez ahead of their latest getaway, where he couldn't stop gushing about the "Ain't Your Mama" singer as well as his own children, daughters Ella, 9, and Natasha, 12, whom he shares with his ex-wife, Cynthia Scurtis.
"Jennifer is one of the most brilliant business minds that I've ever met," the 41-year-old athlete exclaimed. "She's the hardest working lady and, you know, I grew up with a single mother. I have two daughters. I am a big, big promoter of women equality."
