If Mariah Carey is the queen of Christmas, George Michael was the king with his enduring festive hit "Last Christmas." So it's fitting that the pop diva had special words for her late friend following his passing on the holiday, this past Sunday.

The "All I Want for Christmas is You" singer penned an emotional tribute to the iconic musician and took to her website, Mariah's World, on Monday to share it.

"This Christmas, we received the devastating news that beloved singer, songwriter, and music producer George Michael passed away peacefully in his Oxfordshire home. George was only 53 at the time of his passing. He left us way too soon," the pop singer began.

Carey continued with references to the '80s heartthrob's impressive body of work. "He was a genius that gave us classics like "Faith" as well as boundary pushing singles "I Want Your Sex" and "Father Figure." He also gave us the FIRST modern Christmas classic with "Last Christmas."

And while the "Touch My Body" hitmaker is a pop superstar in her own right, she admittedly still gets starstruck. In her post, the 46-year-old recalled a fan-girl moment when Michael, who originally wrote "One More Try" before she recorded her own rendition of the hit, tweeted her to compliment her on her vocals.

"George Michael was an original. He changed music and his music changed lives," she wrote.

"We'll continue to mourn the loss of an incredible artist and friend but his music will keep us smiling and dancing, forever," Carey concluded. "Rest in Peace, George."
