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."
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.
