Mariah Carey Just Signed Rihanna's Boob—And Rihanna's Reaction Is Everything

Mariah Carey made quite an impression on pop sensation Rihanna—right on her left boob.

Carey embarked on her Christmas Time tour on November 6 to celebrate the 30th anniversary of her iconic Merry Christmas album.

At the final show of her tour in New York City, the "All I Want For Christmas Is You" singer saw that pop sensation Rihanna was among the lucky concertgoers to see her perform holiday favorites with her smash hits like "Emotions" and "Hero."

The two hitmakers had the most epic interaction when Carey autographed Rihanna's breast with a red Sharpie, prompting the "Umbrella" singer to grab Carey's mic and inform fans:

“Mariah Carey is signing my tit, y’all.”

It was a night Rihanna is sure never to forget.

"Wow, this is iconic," said Rihanna the moment the Sharpie touched skin.

Here is a clip of the epic breast signing.

The moment had the internet having "emotions."

Rihanna has been a longtime fan of the Songbird Supreme.

The Barbadian singer said in a 2015 interview about the music idols who inspired her, including Carey.

“I was always drawn to music and singing. By the time I was eight, I knew I wanted to sing," she said, adding:

"I loved Mariah Carey, Celine Dion, Bob Marley. I would watch their videos all day long on TV because that’s what they would play in the Caribbean."

"I would start mimicking everything I heard, everything Mariah did, I would try to do.”

After having 14 number-one singles on the Billboard Hot 100 and becoming one of the best-selling recording artists of all time, Rihanna seems to have received her idol's fabulous seal of approval.
