Sneak peek: Oprah grills Lindsay Lohan

Tough Oprah sat down with troubled Lindsay Lohan to tape the actress' first post-rehab interview. A tiny teaser arrived on the Web on Sunday.

"Are you an addict?" asks Oprah sternly.

And she throws this question LiLo's way: "What does it feel like to be both an adjective and a verb for child star gone wrong?"

We don't get to see any of Lohan's answers.

TMZ reports that Lohan is traveling with a sober coach and is asking that all alcohol be removed from wherever she is staying. This week, TMZ, says she's at the Beverly Hills Hotel.

The Oprah's Next Chapter episode featuring Lohan, who completed her 90-day court-ordered rehab last week, will air Aug. 18 at 9 p.m. on OWN. The network will also follow the former Disney star for an eight-episode docu-series.

Meanwhile, you can see Lohan's guest-hosting stint on Chelsea Lately tonight on E! at 11 p.m. ET.
