Two months after separating, Jennifer Lopez and Casper Smart could be trying to rekindle their romance.

The two were spotted hanging out together in a white convertible in Los Angeles on Monday. However, the "Waiting for Tonight" singer apparently did not want to be seen, because she ducked down in the passenger seat after realizing the paparazzi were taking pictures.

Despite trying to spend quality time together, a source told E! Online that the 45-year-old singer and her young beau are "not back together," but are still friends. A second source confirmed that the two were just friends and that there is "nothing romantic going on between the two of them."

"Casper has an enormous amount of respect for Jennifer and her kids," an insider told E! Online. "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."

Lopez and her 27-year-old former boy-toy were together for two and a half years before splitting earlier this year. At the time of their break-up, it was rumored that Smart cheated on Lopez with transsexual model Sofie Vissa, but he has denied all claims and even threatened to sue.

Lopez was recently linked to former "Dancing With the Stars" professional Maksim Chmerkovskiy. The two were spotted a night club in together in July and then celebrating Lopez's 45th birthday. However, a source close to the singer said their relationship is purely platonic.

"There has been a date here and there, but really they are good friends before anything else," a source told E! Online. "Maks asks her for advice, and she thinks he is super-talented and very hot. Obviously, that is hard to ignore. She thinks he is great, but she is being very careful."
