Nick Cannon Shares Thoughts on Mariah Carey's Viral Moment with Rihanna

Nick Cannon recently opened up about a viral moment involving his ex-wife, Mariah Carey, and Rihanna. The talk started after Mariah, 55, signed Rihanna's breast during her Christmas Time tour at the Barclays Center in Brooklyn earlier this week.

Cannon, 44, who was volunteering at the Los Angeles Mission on Friday, shared his excitement with TMZ. "I was there! It was amazing," he said, adding, "Yeah ... that was hot."

The father of 12, who shares 13-year-old twins Moroccan and Monroe with Carey, said he didn’t discuss the moment with her but thought it was “cool” how Mariah made time for her fans and Rihanna. “It was dope that Mariah went into the audience, and they did that. That was super cool," Cannon said.

The viral moment happened on Dec. 17 when Mariah spotted Rihanna in the crowd during her show. She went over to greet her and signed her autograph on Rihanna’s breast, making the crowd go wild. Rihanna even joked into the mic, "Mariah Carey is signing my tit!"

This wasn’t the only memorable moment from the tour. Earlier, on Dec. 9, Mariah's twins surprised her on stage in Raleigh, North Carolina, with a bouquet of flowers to celebrate her holiday classic, All I Want for Christmas Is You, topping the Billboard Hot 100 chart again.

In a recent interview with PEOPLE, Mariah also shared a fun hobby she picked up with her son Moroccan. She revealed that watching him play Fortnite inspired her to join the game. “My Fortnite character is basically me with some cool outfits. It’s really cute,” she said, adding that her virtual character even dances to her famous Christmas song.

From surprise onstage appearances to viral fan moments, Mariah's holiday season continues to shine as bright as ever.
