In an exclusive interview with PEOPLE, Mariah Carey says she can't be called a diva because she returned to the crowd to greet Rihanna at her Tuesday, Dec. 17 show in Brooklyn.

All Mariah Carey wants for Christmas is to no longer be dubbed a “diva” after descending into the crowd to autograph Rihanna’s breast.

Stars collided at the Barclays Center in New York City on Tuesday night, as an epic moment captured on video between two music icons has everyone talking.

The 'Masked Singer' host and 'All I Want for Christmas Is You' singer were married for six years before splitting in 2014

As seen in this video, Rihanna was at the show when she got Carey’s attention and got her signature in red Sharpie on her left breast. As Carey signed, Rihanna said, “Wow, this is iconic.” She then grabbed the mic and told the audience, “Mariah Carey is signing my tit, y’all.”

On Tuesday, clips from Mariah’s concert shows her stopping the show to say hello to Rihanna, who says almost immediately that she wants Carey’s signature. After locating a Sharpie, Rihanna tells Carey, "Sign my tit, because my man made me get you."

Rihanna attended Mariah Carey’s Christmas Time Tour in Brooklyn, where she received a unique gift from the Queen of Christmas herself.
