Lindsay Lohan In Fear of Possible Stalker at Rehab Center

Lindsay Lohan is afraid she's being targeted by a stalker, and the threat is so real that people at Betty Ford are taking measures to protect her, TMZ has learned.

Sources familiar with the situation tell TMZ that Lindsay has been receiving harassing phone calls and text messages from unknown numbers, and the unidentified person behind them has been making disparaging statements about her recovery and her family.

Even scarier, the unknown person is saying he/she knows where Lindsay is staying and is watching her.

Betty Ford officials are so concerned, they're moving their most famous patient to a more secure, private facility, sources tell TMZ.

Betty Ford has limited Lindsay's outings out of concern for her safety, sources say.
