Nick Cannon has filed for divorce from Mariah Carey.

TMZ reported Friday that Cannon filed papers on Dec. 12 to legally finalize his split from Carey. The filing came just days before Carey performed at the Rockefeller Center Christmas Tree Lighting. She allegedly missed a pre-taping for the event because she was working out the settlement with her lawyer.

The actor announced their separation back in August, saying: “There is trouble in paradise. We have been living in separate houses for a few months. My main focus is my kids.”

Around Christmastime, he told “Good Morning America” host Lara Spencer that he and the superstar singer will “always be family.” Carey and Cannon married back in 2008 and are parents to twins, Monroe and Moroccan.

Although he and Carey have been broken up for some time, Cannon said he is not ready to date.

“I’m great. There are a lot of people after me right now. I gotta slow it down. I’m trying to slow it down and stay focused. Family is the first thing and my kids are most important,” he told People magazine in November. Adding: “Obviously the dating thing will come down the line, but right now I’m just slowing down.”

The split is not slowing down Carey’s career. This week, she announced her Las Vegas residency at Caesars Palace.
