Mariah Carey made Rihanna's day by signing her breast during her Christmas concert in New York on Tuesday.
The Queen of Christmas made a triumphant return to the stage at the Barclays Center in Brooklyn after cancelling a few shows due to a bout of the flu.
She made the night one to remember for Umbrella singer Rihanna by walking into the crowd and giving her a special signature.
According to videos posted on social media, the All I Want For Christmas Is You hitmaker signed her autograph on Rihanna's breast in red marker.
Grabbing a microphone, a thrilled Rihanna told the audience, "Mariah Carey is signing my t*t, y'all. This s**t is f**king epic."
After Mariah completed her signature, the Fenty Beauty founder proudly showed off the handiwork and said, "Look at that s**t."
The pop stars exchanged a hug, Rihanna then waved to the onlooking crowd and Mariah continued her show, which marked the final date on her Christmas Time tour.
The concert was thrown into doubt after the Hero singer cancelled her shows in Pennsylvania, New Jersey and New York between 11 to 15 December as she had "come down with the flu" during her favourite time of year.
However, she assured fans earlier this week that she would be well enough to perform in Brooklyn.
"Lambs (fans), thank you for making my #Christmastime so special," she wrote on Instagram. "I've loved singing with you every night, and I can't wait to see you all tomorrow in Brooklyn for the last show of the tour."
