It wasn't for Mardi Gras beads of course; Bialik's intentional nip slip comes a week after Morgan's comments about Susan Sarandon's outfit: a white tuxedo jacket over a black bra that offered a easy view of her cleavage. Morgan, who called Sarandon's look "horribly inappropriate" because she was presenting an award to dead people, sparked a backlash, with people calling him anti-feminist. He was explaining his point of view on Corden when Bialik showed her boobs.
Apparently that offended some people. The Big Bang Theory actress is being hit with sexual harassment - which she wasn't having at all. "I was showing him my cleavage, not my vagina," she tweeted Tuesday. "Get a grip."
Morgan, for his part, took her move in stride too.
"I've never felt less sexually harassed @missmayim. FYI," he tweeted in response.
