Jennifer Lopez and Alex Rodriguez are taking their relationship to the next level. Rumor has it, the "Ain't Your Mama" hitmaker has moved in with the former professional baseball player after just three months of dating.

Sources tell Life & Style that the couple is already talking babies and marriage and J.Lo is taking the first step down that road. "J.Lo asked Alex to live with her in her $28 million mansion in Bel Air, and he agreed," reveals an insider, "The couple have barely spent a moment apart since they started dating and are ready to take things to the next level."

According to the insider, J.Lo made the decision after seeing how well her nine-year-old twins Max and Emme got along with Alex's two daughters, Natasha and Ella, during a recent family getaway.

"Initially she 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," explains the insider, "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."

J.Lo and Alex recently made their first public appearance as a couple at the 2017 Met Gala held at the Metropolitan Museum of Art in N.Y.C. on Monday, May 1.
