Lindsay Lohan living opposite Samantha Ronson

Lindsay Lohan has left the Betty Ford Center after a 90-day rehab stay. The 24-year-old star has moved out of sober living quarters at the clinic’s grounds in Rancho Mirage, California, and into a Los Angeles hotel while she waits to relocate to her new home — which is situated opposite her ex-girlfriend Samantha Ronson’s property.

Removal vans were seen leaving the actress’ West Hollywood apartment and heading to a new four-bedroom house in Venice, and Samantha — who had a volatile on/off relationship with the ‘Mean Girls’ star from September 2008 — is not believed to be happy about her new neighbour.

According to X17 Online, the DJ said, “Trust me, it wasn’t planned. I’m way p***ed off right now.”

“Samantha walked out of the building next door,” a source added. “She was shaking her head and looking disgusted. She kept saying, ‘I didn’t plan it this way.’ ”

As well as four bedrooms, Lindsay’s new home has three-and-a-half bathrooms, a large open patio and two car parking spaces.

Despite being cleared to leave her court-ordered rehabilitation stay — which she was sentenced to for breaching the conditions of her probation relating to a 2007 conviction for driving under the influence — Lindsay will be subject to random drug and alcohol testing with a psychiatrist until a court hearing on February 24.

The troubled star took to her Twitter page on New Year’s Day to reveal her ambition to start 2011 on a positive note.

“Today is the first day of the rest of my life. ‘The future depends on what we do in the present.’ – Mahatma Gandhi … One step at a time,” she wrote.
