Jennifer Lopez and Casper Smart may have been denying their alleged rekindled romance, but a new batch of pictures which surfaced recently suggests otherwise.

Lopez, 45, and Smart, 27, were spotted kissing backstage at the Latina beauty's "American Idol" season 14 taping in West Hollywood, Los Angeles, Daily Mail reports. According to the news outlet, the duo "stayed close to one another" for the whole day and were even together in the choreographer's white convertible after taping for the talent show ended.

The pictures show Smart in low-key clothing, particularly in black from head-to-toe with an equally dark pair of sunglasses and a black sports cap. Lopez, on the other hand, appeared in a more glamorous outfit. The songstress wore a body hugging nude leather House of CB dress paired with Christian Louboutin pumps.

The couple was last seen at the LA premiere of Lopez's new animated film, "Home," which also stars Rihanna, Steve Martin, and Jim Parsons. Daily Mail wrote in another article, that Smart was spotted carrying Lopez's 7-year-old twin son Max at the premiere, presumably to give the "On the Floor" singer a "helping hand" while she stayed close to BFF Leah Remini and daughter Emme.

"We got a lot of ties. We're very close," Smart said about spending time with his ex-girlfriend. "We're friends. We're very good friends." The dancer is reportedly the movie's official choreographer, E! News wrote.

Lopez, on the other hand, insisted to the news outlet that she is still in the dating market. She also claimed in an Us Weekly report that she is currently unattached and that she wants to be alone for now and not deal with any man.

"I mingle a little bit here and there. But, you know, I'm single," the entertainer told E! News.

According to Life & Style Weekly, Lopez and Smart's romance was first expected to be short lived because of their 18-year age difference. The two, however, remained in a relationship for close to four years before breaking up in June 2014. In the past months, Lopez and Smart have been photographed heading to dinner and attending a Kanye West concert.

As for the reason for the two's breakup, Daily Mail wrote that cheating allegations on Smart's part was the one to blame. The choreographer reportedly exchanged messages and sexy photos with two transsexuals, Sofie Vissa, 23, and Xristina Marie, 25, in summer 2014. However, he shut down the rumors by denying that he ever met the two transsexuals "and threatened to sue the websites that first claimed if they did not retract the stories."

According to an insider close to Lopez, she and Smart ended their relationship two months before the cheating accusations began and that the dancer's meet-ups with the transsexuals were "as a single guy," Daily Mail noted.
