Well, that is amusing and I don't know what to think.Clearly, Sharon is a beeyutch on wheels, loves to dish it out, can't take any criticism, and what Megan said is totally true.
But I have to think this was probably staged. I mean, this could hardly be the first time someone said that to Sharon, I'd imagine she could handle herself. If she really gave Megan a reason to sue her, that would be dumb...and horrid as Sharon is, she's not dumb.
She's still a good host for this show, as was the (equally horrible and nasty, but in a different way) Mo'Nique last season.
