Mariah Carey Signs Rihanna's Unexpected Body Part During Final Christmas Concert of the Year

Even celebrities can get a little starstruck from time to time.

On Dec. 17, Rihanna attended Mariah Carey‘s final Christmas concert at the Barclays Center in New York, and she had a surprising request for the Queen of Christmas: signing her breast.

Rihanna’s pal, Jason Lee, owner of the celebrity gossip site Hollywood Unlocked, shared a clip to Instagram showing when Carey approached Rihanna and Lee in the crowd.

“Only she could have Mariah walking back,” Lee said in the clip, referring to Rihanna.

“Should I have her sign my shirt or my t—t?” the “Diamonds” singer asked. 

“I need a signature,” she told Carey. “Who got the Sharpie?”

“Are you filming me on my bad side?” Carey wanted to know. 

“Sign my t—t, because my man made me come get this,” Rihanna said. 

When Carey asked what she should write, Rihanna had a hilariously blunt response.

“Mariah, what the f—k you think? Whatever you want. Wow…this is iconic.”
