Janet Jackson Is Not 'Romantically Involved' With Ex Jermaine Dupri, Source Says

The exes sparked romance rumors when they were spotted at dinner together over the weekend.

Janet Jackson might be spending time with her ex-boyfriend, Jermaine Dupri, but a source close to the singer tells ET that it's strictly platonic.

After wrapping up her her State of the World tour, the 51-year-old musician was spotted having dinner with the 45-year-old producer at STK Atlanta on Sunday, and according to an eyewitness, they were "cuddled" up to one another and holding hands in the VIP area. While their reunion inevitably sparked speculation that they were rekindling their romance, ET's source says Jackson and Dupri are simply "the best of friends," and it's only natural that she would reconnect with him in his hometown.

"They are close and she’ll always have a warm place for him in her heart," the source continues. "Both Janet and Jermaine are warm people, so it’s not unusual that there would be hugging or hand holding, even in public."

According to the source, Jackson and Dupri remained close friends even after their breakup in 2009, and continued to stay in touch when she was married to Wissam Al Mana, whom she split from in April, but is still in the midst of divorce proceedings.

“Janet and Wissam Al Mana’s divorce is not finalized and she would never jeopardize or add fire to what could be a very contentious custody battle” says the source.

Earlier this month, a source close to Jackson told ET that she will take her and Al Mana's son, Eissa, to England for the holidays, where his dad is based. According to the source, Al Mana allowed Jackson to take their son on tour and now he wants him back home with him for the holidays and possibly longer.

“Now that the tour is over they [Jackson and Al Mana] can move forward with their divorce and possibly a very contentious custody battle," the source added. "The couple will be using a mediator for the time being."

ET reached out to Jackson's rep, who had no comment about her recent outing with Dupri.
