Nick Cannon was at home to see his ex-wife Mariah Carey leave its mark Rihanna‘s breasts… and she says more women should follow suit.
We got Nick to do some charity work at Mission LA on Friday, and our photo asked him about the viral video of Mariah’s recent concert.

Nick says looking Mariah Ri Ri’s breast autograph was “hot” … and he hopes it will become a trend.
On a more serious note, Nick says it was really cool of Mariah to leave the stage to go and greet Rihanna at the show … and he gives RiRi some love for supporting the MC.
Nick gives back to the community here for the holidays, and we also asked him what it’s like to play Santa for all his kids, including the twins he shares with Maria.
The kids are getting older, which means presents are getting more expensive… and Nick tells us if he’s putting a cap on his Christmas spending.
