This might be Lindsay Lohan's only wedding day -- so y'all better get a good look!

Last night, the troubled star, who's known more for her bad decisions than her bad acting these days, guest stared on a very special episode of Two Broke Girls and played a demanding, over-the-top bridezilla! Who woulda thunk it?! (Hint hint: the answer is everyone)

On the CBS sitcom, Lindsay plays, Claire, a mercurial, high-maintenance bride-to-be who visits Max (Kat Dennings) and Caroline’s (Beth Behrs) bakery and asks the gals to bake her a cake for her wedding day. But of course things don't go to plan.

"She’s a really funny character," said Lindsay. “I think she’s a bit neurotic. She’s getting married, but she doesn’t know if she wants to and it’s all about the cake."

Maybe it should have been all about the funny -- 'cause judging from these clips, it's not.
