The Waiting For Tonight hitmaker and her ex sent fans wild at the Latin Grammy Awards on 17 November (16) when they briefly embraced and kissed, after Jennifer presented him with the Person of the Year Award at the Las Vegas ceremony.

The following day, it emerged Marc had separated from his wife Shannon De Lima after two years of marriage, and rumours suggested his passionate onstage reunion with Lopez had prompted the model to call it quits.

However, J.Lo's best friend Remini has shut down the speculation, insisting Marc and Shannon had already parted ways before the headline-grabbing performance.

Leah was quizzed about the gossip during an appearance on U.S. talk show Watch What Happens Live on Thursday night (01Dec16) and she took it upon herself to clear up the unfounded claims.

Asked if Jennifer's kiss with Marc had anything to do with his marriage split, the actress replied, "Absolutely not, that is not the reason. Marc's separation had happened already, clearly way before that."

Leah then offered up her thoughts on the headline-grabbing stage appearance.

"I thought it was an innocent kiss between two parents and two friends," she explained. "I love them onstage together, and I love that they still perform (together)."

Jennifer and Marc, who share eight-year-old twins Max and Emme, have remained close since calling time on their seven-year marriage in 2011, and they are currently working together on Lopez's new Spanish-language album.
