Could it be that troubled actress Lindsey Lohan is finally taking a rehab stint seriously?

She's spent 250 days in five rehab facilities since January 2007, including one long court-ordered stint after a failed drug test.

Her most recent rehab stint stems from two misdemeanor charges relating to a traffic accident last summer, and the finding that she violated her shoplifting probation with those convictions. Lohan was charged with reckless driving and lying to a police officer regarding a June 2012 car crash in Santa Monica, California. That arrest is what triggered the probation violation charge.

Since then Lohan has been keeping relatively quiet since she entering the Betty Ford rehab facility three weeks ago. She recently took to the social networking site Twitter to post an inspirational message.

"Somewhere over the rainbow, blue birds fly'...It's up to us to make the best of what we have :)"

Sources close to Lohan have reported that,"She is been attending all of her group and one-on-one counseling sessions."

"Lohan is even rooming with two roommates and getting along with them. People that have visited Lohan claim she looks better than she has in a long time," the source said.

Sources have also reported that Lohan "attends ALL of her group one-on-one counseling sessions at Betty Ford and she's not only taking them seriously, but she's also talking to friends about what she's learned, especially issues involving self-control and reckless impulses."

"The program is getting more complicated and emotional, but she's not shying away."

Even Lohan's mother believes her daughter is in a better state of mind. She spoke to the New York Daily News saying, "Rehab was doing her daughter a world of good."

 "I just spoke to Lindsay at Betty Ford. She's doing great. She's clear, she's happy, she's healthy." Lohan's mother said.
