On Monday, back-up dancer Casper Smart was spotted driving a BMW in Los Angeles with his famous ex, pop superstar Jennifer Lopez, in the front seat. The sighting is sparking rumors that Smart is trying to win J.Lo back since they broke up in June after he allegedly cheated on her with a transsexual, which Smart denied.

Smart was seen hanging out with Lopez and driving around in a white BMW convertible. However, when the couple arrived at Lopez’s house, photographers were waiting to snap pictures, causing her to duck out of view.

A source told Hollywoodlife.com that Smart is doing what he can to win J.Lo back. “Casper is aware of his mistakes and is doing everything to make it up to J.Lo. He is being the same guy he’s always been to her, which she is happy with. The way things are working out is currently so far so good,” they said.

According to the source, Lopez hasn’t gotten over Smart, preferring to return things to how they once were with him and not start a new relationship. Her six-year-old twins with Marc Anthony, Emme and Max, supposedly keep asking about Smart, and the former couple stayed in touch after the split and “remained friendly.” The source further revealed that the two were “working out their differences to hopefully rekindle their romance, or to at least work together again.”

E! News reported, however, that Smart and Lopez were just friends with “nothing romantic going on between the two of them.”

“He still loves her and cares about the kids. Nothing has really changed since they split regarding their relationship and nothing romantic is going on,” a source told E! News.

Lopez has been rumored to be dating Maksim Chmerkovskiy of Dancing With The Stars, who was seen by the singer’s side as she celebrated her 45^th birthday in the Hamptons.
