Lindsay Lohan has hit a whole new level of stupidcrazy. If somebody offered you to do something fun for $550,000 -- you'd JUMP at the chance, right? But not LiLo...that's beneath her.

Lindsay was offered over HALF A MILLION DOLLARS to join the cast of the next season of Dancing With The Stars, ONE OF THE MOST POPULAR SHOWS ON TV, but turned it down because she wants to focus on movies.

Yeah, because she's been plastered all over the silver screen lately, right? Oh wait..my bad..she's just been plastered.
