LINDSAY LOHAN: Rejects Massive Offer From 'Dancing with the Stars'

Lindsay Lohan's ego might be her downfall --, she just shut down a lucrative offer to do "Dancing with the Stars" ... because she doesn't want to do reality TV.

Sources close to Lindsay tell us, the actress was made several offers to join the DWTS cast this upcoming season -- offers that maxed out at $550,000.

But Lindsay -- who still owes hundreds of thousands in back taxes -- shut them down, telling friends she'd never consider doing reality TV ... she wants to stick to films.

But there's one problem -- after "The Canyons" fiasco, she's basically made herself unhireable. And as the saying goes, beggars can't be choosers.

A rep for DWTS says, "We don't comment on casting."

Given the IRS seizing her accounts, one would think she'd snatch that up in a second, but no, she says she'll NEVER do reality TV. Only movies.

The irony/stupidity of that statement is that after Liz & Dick and The Canyons, her film stock is going down faster than a drunk Lindsay on Max George.

Good luck, LiLo.
