Lindsay Lohan has been taking visits from her ex-girlfriend Samantha Ronson in rehab.

The troubled actress is completing a court-ordered stay at the Betty Ford Center in Los Angeles after failing drug tests, and has been seen a number of times by the DJ since she was admitted in September.

A source close to them both told E! News: "I've spotted Samantha there a few times, which is good. Lindsay seems to be in a really good head space.

"Not sure how to explain it, but she seems lighter, like a weight has been taken off. She's come to terms with how bad things got and no longer wants that for her life."

Lindsay is said to be making good progress at the facility and the friend added she is looking "amazing" and is working out every day.

She has progressed to the stage where she is even allowed day passes for visits outside of the treatment centre to her apartment, and was allowed to spend 15 hours with her family and friends for thanksgiving last Thursday.

It is not known if Lindsay and Sam - who dated between 2008 and 2009 - met on that day, but Sam did tweet: "This thanksgiving I am thankful that I'm spending today with someone else's family. Everyone else's dysfunctions always seem so much 'cuter'. (sic)"

As a another sign of her continuing progress, the 'Machete' actress and her sober house at the Betty Ford Centre are to be awarded a 'Sober Shine Award' for staying clean.

Lindsay, 24, is scheduled to stay at the clinic until January 2011.
