Jennifer Lopez is reportedly dating Maksim Chmerkovskiy. The singer and the 'Dancing with the Stars' professional met through the 'On the Floor' hitmaker's best friend Leah Remini and though things are going well already, they want to take their romance slowly. A source said: "It's really new." Another source said: "They are friends and have been talking." The 'First Love' singer previously danced with 34-year-old Maksim at the American Music Awards last November in a routine which saw him spin her over his head, and though nothing happened between them at the time, insiders say their chemistry was undeniable. Both Jennifer and Maxim were at the dancer's brother Val's birthday party at the Redbury Hotel in Los Angeles in late March and were described as "inseparable" during the evening. A source said: "At one point, he put his arm around her waist and they seemed to be locked in a very passionate conversation." Friends think it is now only a matter of time before the 'American Idol' star goes public with her new romance. Asked if they will be out as a couple any time soon, a source said: "I think they could. Who knows what will happen?”
