In a hilarious and unforgettable moment during Mariah Carey’s final stop on her Christmas tour, Rihanna had fans in stitches when she asked the Queen of Christmas to sign a very unconventional place—her breast! The now-viral moment was shared by media personality Jason Lee on Instagram and quickly spread across social media.

As the two music legends interacted backstage, Rihanna, with a cheeky grin, asked Mariah for an autograph on her chest. The funny request was inspired by Rihanna’s boyfriend, ASAP Rocky, who can be heard in the background urging her to go for it. “You want to get it right, you know, everybody’s watching,” he said with a smile.

Rihanna enthusiastically asked, “Hello, Mariah, I need a signature. Who has the Sharpie?” Mariah, always the good sport, laughed and graciously agreed to sign her chest, saying, “My Mariah, whatever you want.” The playful moment between the two stars was filled with laughter and lightheartedness, capturing the attention of fans everywhere.

While Mariah has long been known as the “Queen of Christmas,” she humbly noted that the title was given to her by fans, not something she ever claimed herself. “I never called myself queen of Christmas,” Mariah explained. “Other people started calling me queen of Christmas, and I was like, ‘Oh, that’s so cute.’”

Rihanna, a long-time fan of Mariah’s music, shared that one of her Christmas traditions is to listen to Mariah’s iconic hit “All I Want for Christmas Is You” every year. “I’m going to eat a lot of food and listen to Mariah Carey,” Rihanna said, showing just how much the holiday season means to her.

This viral interaction was a fun, full-circle moment for Rihanna, who, 15 years after first hearing Mariah’s Christmas music, had the chance to meet her idol in person. Their playful exchange will surely go down in history as one of the most memorable moments of Mariah’s Christmas tour.
