Just hours after her return to jail, Lindsay Lohan's close friend, The A-List: New York reality star Derek Lloyd Saathoff, is praying her latest legal drama will finally force the troubled actress to change her life - for good. "I hope this will be the end of it," Derek exclusively tells In Touch. "It's difficult to watch; I just want the best for her. She will hopefully turn over a new leaf." After meeting with Lindsay just last week, the modeling agent thought his friend of seven years was on the straight and narrow. "When I saw her, I thought things had changed. She was optimistic that she could pull things together," he adds. What a difference a week makes! Lindsay, who recently violated her probation by failing two drug tests, is now in custody in Lynwood, Calif., after being denied bail.
