Mariah Carey and Nick Cannon Celebrate Twins' 15th Birthday

Pop icon Mariah Carey and TV host Nick Cannon came together this week to celebrate a major milestone: the 15th birthday of their twins, Monroe and Moroccan.

The "Demois Babies" marked the occasion with back-to-back family parties and touching social media tributes.

Carey shared photos on Instagram Thursday, April 30, showing her children wearing custom Disney-inspired T-shirts that read “Rocky & Roe 15th Birthday.” She also posted a video of the siblings blowing out candles on their birthday cakes, captioning it: “Happy Birthday, Roc & Roe! I love you so much Mom.”

The twins responded with their own heartfelt messages in the comments. “I love you mom!” Monroe wrote, while Moroccan added: “Love you mom, I’m so grateful.”

Nick Cannon shared highlights from a separate celebration, which included an adrenaline-filled trip to Six Flags Magic Mountain. His video post captured a confetti-filled cake moment for the teenagers.

“Got two 15-year-olds on my hands now!!!! Happy Birthday to my first firstborns!” Cannon wrote. “I thank God and you for allowing me to be your Dad! I love you Roc and Roe!”

Fans quickly flooded the posts with well-wishes, with many noting how much the twins have grown to resemble their famous parents in recent years.
