On Monday's Chelsea Lately, the Monsters University star got a little handsy (he had permission!) with the late-night host's boobs.
Sean first pointed out that Chelsea's desk "is unusually high," mimicked hoisting up his chest and noted "you could rest them [your boobs] on it!"
As Chelsea pondered this, she mused aloud about her girls. "My breasts—sometimes they're very large," she said. "At this time of month, they're very small, as you can see."
But Sean didn't think so. "Well from here, they're very large," he quipped.
Chelsea couldn't help but smile at the compliment, but flattery wasn't the only thing the Will and Grace alum wanted to accomplish.
He reached towards her, asking very forwardly, "May I?"
"Of course!" Chelsea said, standing up to meet his grasp. "You can touch 'em!"
Sean gave her girls a good squeeze, which Chelsea didn't mind whatsoever. "You're pretty much the only man in this business who hasn't [touched them]," she joked.
Sean, who came out as a gay man in 2010, told Chelsea post-boob grab, "They're very confusing to me."
Well, there's no one better than Chelsea to give a lesson in lady parts!
