She was ready for her close-up. Oprah Winfrey’s interview with Lindsay Lohan aired last night, with Lindsay insisting she has put her hard-partying ways behind her. “I’m my own worst enemy and I know that.” Lohan said she had not only stopped drinking, but also taking Adderall, the prescription drug she had been taking since she was a child. Lohan insisted she had only taken cocaine “10 to 15 times” and “it was a party thing” and she never injected any drugs. Fresh off her well-reviewed performance in The Canyons, Lohan said the happiest day of her life was the day she got the role in The Parent Trap when she was 10 years old, and she said she wants to “just work really hard and prove myself in the way I did before and I lost it.” (via The Daily Beast)
