Nick Cannon reacts to ex-wife Mariah Carey, Rihanna's racy moment

Nick Cannon thinks ex-wife Mariah Carey raised the temperature when she signed on Rihanna's chest last week.

The comedian, 44, was speaking of the popular moment with TMZ on Friday—gushing over Carey, 55, signing Rihanna's breast with a marker when she spotted the Diamond hitmaker in the crowd at her last show and walked to her.

"I was there! It was amazing!" Cannon said of the "impromptu" moment, further adding, "Yeah... that was hot."

The father of 12–who shares 13-year-old twins Moroccan and Monroe with Carey–remarked that it was "dope that she stopped in the middle of the show."

"I thought it was dope that Rihanna came. I thought it was dope that Mariah went down into the audience and they did that... that was just super cool," he told the outlet.

The Tuesday interaction with Rihanna was one of several notable moments during Carey's Christmas Time tour. 

"Mariah Carey is signing my tit," the Fenty Beauty founder shouted excitedly into Carey's microphone.

Cannon is also a dad to sons Golden, 7, and Rise, 2, and daughter Powerful, 3, with Brittany Bell; twins Zion and Zillion, 3, and daughter Beautiful, 2, with Abby De La Rosa; daughter Onyx, 2, with LaNisha Cole; son Legendary, 2, with Bre Tiesi; and daughter Halo, 2, with model Alyssa Scott, with whom he also welcomed son, Zen, but lost him to brain cancer at just five months.
