First look: Lindsay Lohan gets grilled by Oprah Winfrey

Lindsay Lohan sat down with Oprah Winfrey for her first post-rehab interview, and from the looks of it no question was off-limits.

In a teaser that arrived online Sunday night, Winfrey is seen asking Lohan, point-blank, "Are you an addict?"

She also asks the 27-year-old actress this: "What does it feel like to be both an adjective and a verb for child star gone wrong?"

We don't get to see either of Lohan's responses.

During an appearance Monday on "CBS This Morning," Winfrey said that when she sat down with Lohan, she felt the troubled star "was honest, that she was authentic and that she is ready." (Watch the video at left.)

The Lohan episode of "Oprah's Next Chapter" will air Sunday, Aug. 18, at 9 p.m. ET on OWN.

In the meantime, you can catch a glimpse of post-rehab Lohan when she guest-hosts "Chelsea Lately" Monday night on E! at 11 p.m. ET.
