Lindsay Lohan is her 'own worst enemy'

'The Canyons' star, who completed 90-days of court-ordered treatment in rehab on July 31, as part of a plea deal to avoid jail after violating her probation by lying to police about driving during a car accident last year, appears to be eager to take responsibility for her problems and legal troubles. In a sneak peak teaser of her new interview with Oprah Winfrey for 'Oprah's Next Chapter', the 27-year-old actress is asked by the talk show legend: "Do you think you can turn things around?" She also asks the actress: "What is it that you're addicted to?" The actress emotionally replies: "I'm my own worst enemy. I know that." Oprah, 59, has taken a vested interest in Lindsay's well being following her well-documented troubles as the actress is now filming a documentary series about her road to recovery for Oprah's TV channel, OWN.
 Shortly after their recent interview, Oprah insisted that she believes Lindsay is ready to move on with her life. She previously said: "I just interviewed her, and I was deeply moved by her desire to move forward in her life at this time ... I really do believe that she's ready." She also said she felt the 'Mean Girls' star was "honest" and "authentic" during their chat, adding: "She looked good. She looked strong. She looked healthy."
