Moving Company Betrays Lindsay Lohan

One of the movers who helped pack up Lindsay Lohan's mountain of crap in her Venice home is now trying to sell photos of the actress' personal belongings ... TMZ has learned.

According to sources, the mover in question took photographs of Lindsay's stuff while he was piling it into storage -- and is now trying to sell the pics ... as well as information about the storage facility Lindsay is using ... and even where she eventually plans to move.

Sources tell TMZ, Lindsay's camp is aware of the situation and is currently working to find out who's behind the leak attempt.

Lindsay's people are especially freaked because the actress has made it a priority to keep a low profile the last few weeks -- following a trespasser scare on her Venice property New Year's Day.

We're told Lindsay is also afraid people might try to track down her belongings in storage and try to steal things. So far, we're told police have not been involved.
