Nick Cannon is apparently cool with Mariah Carey's plans to remarry.
The 35-year-old comedian took to Instagram on Saturday to congratulate his ex-wife and her new beau, Australian billionaire businessman James Packer, on their engagement in a "hilarious" way.

Cannon -- who has joked about his relationship with Carey plenty of times since they called it quits -- poked fun at himself by sharing a fan-created meme that shows him on a hospital bed with Kevin Hart by his side. The photo, which was taken from their BET faux-reality show, Real Husbands of Hollywood, reads "It's just a ring Nick..."
"Ha! This made me laugh out loud for real!!! HILARIOUS! #AllLove," Cannon captioned it. "Congrats to @MariahCarey and James! May God Bless Your Future Union...#GreatPeople #GreatCouple."

Packer, 48, popped the question to Carey Thursday night in New York City. The two started dating over the summer after meeting at the Hercules premiere in Aspen, Colorado, and Carey hasn't stopped gushing over him since.
Cannon and Carey, 45, filed for divorce in December 2014 after six years of marriage. While their relationship was rocky directly following the split, they have since overcome their differences and are on good terms for the sake of their children, 4-year-old twins Monroe and Moroccan. The two even spent the holidays together, with both sharing photos from their family gathering on social media.
Shortly after news of Carey's engagement broke, ET obtained photos of the "We Belong Together" singer’s massive 35-carat diamond sparkler, one of the biggest and most expensive rocks ever worn by a celebrity.
