Lindsay Lohan has reportedly been a model patient at Betty Ford Clinic in Rancho Mirage, Calif., since arriving at the facility on May 2, according to TMZ.
In her first tweet in a month, the Scary Movie 5 star shared the following message with her followers: "Somewhere over the rainbow, blue birds fly"...it's up to us to make the best of what we have :)"
The tweet, which referenced the song Over the Rainbow from The Wizard of Oz, also linked to an app called Just Sing It.
The actress attended all her group and one-on-one counseling sessions at the clinic thus far, sources said. Lohan also spoke to friends about what she has learned, especially issues regarding self-control and reckless impulses. She has been sharing a room with two roommates at Ford and is apparently getting along with both. Visitors who have seen Lohan said she looks better than she has in a long time.
Los Angeles Supreme Court Judge James Dubney ordered the 26-year-old the actress to spend 90 days in lock-down in rehab as part of her sentence for reckless driving. She received the sentence on March 18, after violating her probation by lying to police about a car accident in Santa Monica last year.
The Mean Girls star did not contest the charges in March and she checked into the rehab as ordered. She also agreed to serve 30 days of community service and 18 months in psychotherapy.
Before checking into rehab, Lohan appeared with Charlie Sheen on the red carpet on April 11 for the Hollywood premiere of the film Scary Movie 5. The two have cameos as a couple in the film. Scary Movie 5 opened to a relatively poor reception and earned only $15.2 million its opening weekend.
This is Lohan's sixth time in rehab.
