Lindsay Lohan has moved into an apartment next to Samantha Ronson, her ex-girlfriend, in a bizarre move about which Ronson is allegedly pretty unhappy.

Lohan was discharged from rehab yesterday after spending three months fighting her drug and alcohol addictions.

The actress has surprised many by choosing to move into an apartment next door to DJ Sam Ronson, sister of uber-producer Mark Ronson. Li-Lo and Sam dated between 2008 and 2009 and are seemingly not on the best of terms.

When asked what she thought about Lohan moving in next door to her Venice Beach apartment, Ronson ranted to US Weekly:

“Trust me, it wasn’t planned.”

“I’m way too pissed off right now.”

Lindsay, on the other hand, seemed all peace and love on New Year’s Day when she Tweeted a (rather worn-out) Gandhi quote: “Today is the first day of the rest of my life.”

Lohan needs to keep on the straight and narrow as she will be subjected to random drug and alcohol tests until her next court hearing on February 24.
