Lindsay Lohan has said she has no doubt that checking into rehab after her DUI arrest in May was the best thing to do.

Lindsay went thought a 30-day treatment programme at Promises in Malibu during June and is currently in the facility’s extended care scheme to help her integrate back into her normal life.

She told Tatler magazine recently: “[The arrest and subsequent rehab has] changed my life.”

“I didn’t have a good grip on it and I needed to get my s*** together. I was going out too much and I had too much pressure on my shoulders.”

“I was not that happy and I needed to go to that place to be happy.”

She added that she has now developed ways to deal with the pressure caused by her fame: “If I get stressed out, I say a serenity prayer. I meditate too.”

She might need those prayers and meditation skills once she hears that one of her MySpace friends has reportedly sold private messages to Star magazine.

According to the publication, one of the 75 people given access to her private blog has reported that Lindsay had a “heated” exchange with DJ friend Samantha Ronson over the messenging system, at one point telling her: “Babe, if I don’t have you in my life then I should just go die. … I want to marry you and have children with you.”

“I love you. - [signed] Lindsay Ronson.”
