Happy Birthday, Monroe and Moroccan!

Mariah Carey and Nick Cannon’s twins are getting so big — and it’s hard to believe that the adorable little boy and little girl just turned six years old! Even though they’re not together anymore, that didn’t stop the former couple from posting heartfelt tributes to their kids on their birthday.

Nick shared an adorable throwback photo of Roc and Roe from when they were still tiny little babies — wearing adorable pink and blue outfits. He shared another throwback photo of his baby girl and called her his “queen” in the caption, and he called his son a “real rock star” in the caption of his tribute.

The 36-year-old also shared an adorable snap from the twins’ birthday party — which featured a Disney theme! In the shot, Roe wore a sparkling princess tiara and her brother wore a hat with mouse ears and they each got their won personalized cake — Minnie Mouse-themed for Roe and Mickey Mouse-themed for Roc.

Though it’s unclear whether Mariah and Nick celebrated their kids’ birthday together since she didn’t share any photos from their party, she did take the time to post a throwback photo of her own! In the shot, the 47-year-old held her newborn babies in both of her arms.

“I can't believe it's been six years since you two came into this world to the live version of Fantasy…the applause!!! I love you both more each day. You are the light of my life,” the “I Don’t” singer wrote in the caption.

The twins definitely seemed to have a blast at their party, and they’ve also been spotted out with both of their parents a lot more frequently. Ever since Mariah split from her boyfriend Bryan Tanaka, she’s been spending a lot more time with her ex-husband — so much that they sparked dating rumors. Nick addressed the rumors during a recent family outing.

"We've always been official," he told TMZ.
