Cannon posted a funny photo on Instagram on Friday poking fun at those who expect him to be resentful of his ex-wife's happy news.
"Ha! This made me laugh out loud for real!!! HILARIOUS! #AllLove Congrats to @MariahCarey and James! May God Bless Your Future Union... #GreatPeople #GreatCouple," he captioned the picture of himself passed out in a hospital bed with Kevin Hart telling him, "It's just a ring Nick....."
Nick Cannon Talks Co-Parenting with Mariah Carey
Carey, with whom Cannon shares 4-year-old twins Monroe and Moroccan, and billionaire Australian businessman James Packer got engaged on Thursday, when Packer proposed with an "epic" 35-carat diamond ring.
For his part, Cannon, 35, recently shared that he has no plans to remarry.
"I feel like marriage isn't for everyone," he told DuJour magazine. "There's like a 50/50 chance of a marriage working. If it didn't work out for you the first time, and you still survived it, you probably shouldn't do it again."
