The Wild 'N Out star posted the sweet snap alongside a message on raising his daughter to be a "sophisticated intellectual," and a lighthearted warning for any "ruffneck kindergarteners" that may have a crush on her.
"Miss Monroe loves her glasses and I hope she never takes them off!!" he captioned a twinning selfie where he also wears glasses. 'A sophisticated intellectual is what I'm trying to raise here and these glasses keep them little grimy ruffneck kindergarteners away from my baby!! LOL."
"FYI My Shotgun is registered!!," Cannon jokingly added.
Aside from spending quality time with his kids, Cannon weighed in on Carey's recent split with her backup dancer, Bryan Tanaka. When ET caught up with the 36-year-old comedian on Monday, he addressed rumors that Tanaka was jealous of his co-parenting relationship with Carey.
"Most men are jealous of me. I'm joking," Cannon quipped before making it clear that he knew "nothing" about the breakup.
The doting dad went on the praise Carey's parenting skills: "For me, at the end of the day, she's an amazing mother and we focus on our kids," he said. "That's never going to change no matter who's in my life or who's in her life. We have kids together, so we'll always be family."
