The sweet photo comes less than two weeks after Life & Style reported that the 47-year-old and her new boyfriend, Alex Rodriguez, are moving in together. “J.Lo asked Alex to live with her in her $28 million mansion in Bel Air, and he agreed,” an insider revealed. “The couple have barely spent a moment apart since they started dating and are ready to take things to the next level.”

In fact, her twins have already bonded with A-Rod’s two daughters, Natasha, 12, and Ella, 9, from his marriage to Cynthia Scurtis. “Initially [J.Lo] was concerned there would be a rivalry since the children are all so close in age and are used to being the center of their parents’ world,” the insider explained. “But as soon as the four kids met, it was like one big, happy family. J.Lo has always wanted to have a large family, so it’s a dream come true for her.”

The Shades of Blue actress previously admitted that she’d “love to have twins again,” but for now, she’s happily co-parenting with “great friend” and ex, Marc Anthony.

“I’m always going to be there for him, he’s always going to be there for me. We share something very special in the kids — and we’re there for them, and that’s the main thing,” Jen said of her former spouse in March. “The kids get to spend time with the two of us more together and see us working together and it’s good for them, it’s just good for the whole family.”
