Rehab changed Lindsay's life

Lindsay Lohan tells Tatler mag that she is a changed woman since checking into rehab in Malibu in May. "I didn't have a good grip on [life] and I needed to get my s**t together," the Georgia Rule star says. "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. If I get stressed out I say a serenity prayer. I meditate too." Lohan says she also uses Machiavelli's The Prince, written in the sixteenth century by the political philosopher, as a self-help guide.
