Mariah Carey signs Rihanna’s bre.ast

For Mariah Carey, it’s always work, work, work, work, work

But this time, the singer, 55, had a special guest. Rihanna made an appearance during the final stop of Carey’s Christmas Time tour at the Barclays Center in New York City on Tuesday, Dec. 17.

“I need a signature. Who has a Sharpie? Sign my tit!” the superstar, 36, can be heard telling Carey in a video posted to social media.

Carey signed her first name with a red Sharpie on Rihanna’s bre.ast. The “Diamonds” singer then grabbed Carey’s microphone and addressed the audience.

“Mariah Carey is signing my tit, y’all! This s–t is f–king epic!” Rihanna said before showing her new autograph to the camera and hugging the performer.
