Oprah Winfrey has landed another TV coup - she'll be the first to interview Lindsay Lohan after the troubled actress walks free from court-ordered rehab next month (Aug13).

The Mean Girls star was sentenced to serve 90 days in a treatment facility earlier this year (13), and her time will be up at the beginning of August.

Lohan will return to public life with a sit-down Oprah chat for the TV titan's OWN network.

Confirming the big news, a Winfrey spokeswoman says, "OWN will air an exclusive interview with Oprah and Lindsay Lohan that will tape and air in August."

Lohan has also agreed to front an "eight-part documentary series", which will revolve around the actress' efforts to stay healthy and make a career comeback after her three-month rehab stint, for the network in 2014
