Lindsay Lohan will be sent to jail if she decides to bolt from the Betty Ford Center in Rancho Mirage, Calif., Breaking Celebrity News has exclusively learned.

As we reported earlier, a terrified Lohan is threatening to quit the facility and move to another rehab after doctors refused to supply her with the drug Adderall.

If she does, the 26-year-old will be hauled before Judge James Dabney who had previously told the actress' attorney, Shawn Holley, that he expected her to honor the plea deal on charges of reckless driving and lying to police about a car crash.
