Lindsay Lohan's mother hopes the troubled star will turn her life around with the help of Tv titan Oprah Winfrey.

The Mean Girls star will sit down for a candid interview with the media mogul upon completing her current 90-day stint in rehab next month (Aug13).

She has also signed up to film an eight-part reality series for Winfrey's Own network, and Dina Lohan hopes having the queen of daytime Tv on-side will finally get her daughter back on track.

She tells the New York Post's gossip column Page Six, "If there's any mentor you could choose, there's nobody better than Oprah. This is a great opportunity for Lindsay. We are all very excited about it."
