Don Lemon breaks into uncontrollable hysterics at just the mention of Omarosa's name -- and then he got worse

During a Thursday panel discussion with Symone Sanders and Scott Jennings, CNN host Don Lemon tried to talk about Omarosa Manigault-Newman, but it didn't quite work out the way he intended.

"Don, it's Black History Month. We gotta talk about Omarosa?" Sanders asked.

It prompted Lemon to break into hysterics. He laughed, he snorted, his eyes watered and someone had to hand him a tissue. Even after cutting to the video of the former White House aide on "Celebrity Big Brother," Lemon still struggled not to laugh.
