After 30 days, Lindsay Lohan has left the Betty Ford Clinic to complete the remainder of her 90-day court mandated rehab stint at the Cliffside Center in Malibu. And everyone -- prosecutors included -- signed off on the deal.

This time around, LiLo was actually smart and made sure to get her new home-away-from-home approved by the judge, prosecutors and her lawyer before just up and switching facilities because she felt like it.

All involved parties agreed that the move was beneficial, as Betty Ford is more of a 30-day rehab program while Cliffside is better suited for longer stays -- and after arriving yesterday, La Lohan is already said to be already settling in nicely. (Yes, even without her Adderall, which she probably won't be allowed to have at Cliffside either.)
