It looks like Jennifer Lopez is digging into the past in order to plan her future. After announcing her split from husband Marc Anthony, Lopez has fallen back into the arms of music mogul Sean "Diddy" Combs. A source close to Diddy tells BET.com that Jennifer is "the love of his life" and he's so excited to be back with his "fantasy girl." Not everyone in Diddy's circle is happy about the reunion, though. Our source is worried that he will end up hurt, especially since she wasn't there for Diddy when he "needed Jennifer the most."

Lopez, 42, and Combs, 41, had an intense love affair in the '90s that ended shortly after the 1999 shooting at Club New York that left Diddy on trial for weapons charges (he was found not guilty). Lopez discussed her romance with Diddy on VHI's Behind the Music. "It was very fast," she said, "but we did have a connection. We did fall in love and we were very close.”

A source close to Jennifer tells BET.com, "Puff wouldn't be my first choice for her, but then again he was always very supportive of her sex symbol image and never got mad when she wore sexy clothes. He actually encouraged it." And now that Jennifer and Diddy are spending time together again, our source wouldn't be surprised if they show up on a red carpet together very soon.
