Lindsay Lohan -- Possible Slumber Party in Jail

Lindsay Lohan could spend as much as one night in jail -- this according to L.A. County Sheriff's Department spokesperson Steve Whitmore ... but he insists, Lindsay is NOT getting special treatment.

TMZ broke the story ... Lindsay will likely get out of jail in minutes due to overcrowding, but Whitmore claims, she could be stuck behind bars for hours -- even overnight -- depending on when she decides to check herself in.

Whitmore answered several questions about Lindsay's impending jail sentence earlier today during a news conference -- but despite claims Lindsay is getting off easy ... Whitmore insists she's getting the same treatment as everyone else.
