Jennifer Lopez has only been dating Alex Rodriguez for a few weeks, but the singer is already spending quality time with his family!

Over the weekend, the retired baseball player’s sister, Susy Dunand, shared a couple of selfies with the mother-of-two, including one with the caption, “Simply sweet!!!”

The hangout came just one day after the new couple was spotted grabbing dinner in Miami. “She is having a great time with her kids and A-Rod — she’s very giggly when she talks about him. It actually seems like they’re getting more serious by the minute,” a source told People magazine. “Jennifer thinks the world of A-Rod. She is very impressed and gushes about what a gentleman he is. She’s trying to take things slowly, but she is very excited.”

As evidenced by photos of the duo at a Yankees game in 2005, the stars “have known each other for years, but the timing wasn’t right,” a different insider revealed. J.Lo was with Marc Anthony at the time, while A-Rod was married to ex Cynthia Scurtis. But the pair recently bonded over their children.

Jennifer has yet to speak out about the relationship, though she seemingly confirmed they were dating when she accidentally posted a selfie with a man who fans believed was the 41-year-old. The nickname “J-Rod” has since been born.

The Shades of Blue actress, 47, was recently linked to Drake, who name drops his famous ex on the new playlist More Life. “I drunk text J.Lo / Old number, so it bounce back,” the 30-year-old raps, suggesting that the brunette beauty changed her number following their split. The Canadian previously admitted that their romance fizzled, telling the crowd at one of his concerts, "I can’t even make a relationship last seven weeks.”
