Lindsay Lohan will sit down for a heart-to-heart with Oprah Winfrey, which airs Sunday, August 18 on O for Oprah’s Next Chapter (OWN, 8/9c.) Lohan appears to answer the tough questions, while looking amazing in a form-fitting tangerine-colored dress.

In this new preview of the interview, Oprah asks "Are you an addict?" and "What does it feel like to be both an adjective and a verb for child-star-gone-wrong?" (Watch the preview below.)

After the interview, Lohan will appear on the network again in 2014 for her own eight-episode docu-series.

Ahead of her appearance on Winfrey's series, she will appear as a guest host of Chelsea Lately on Monday, August 5. In addition to poking fun of One Direction Harry Styles' sexuality, she'll also have some fun at Kristen Stewart's expense. In one joke, the actress is discussing the latest celebrity gossip when an item about Stewart yelled at the paparazzi comes up.

Lohan's response? "I'm just excited that Kristen Stewart, you know, finally showed some emotion," she says. "No, I really do love her. She's awesome. I'm a Kristen Stewart fan."

But, she doesn't leave it alone there, adding, "I will say this, of course she hates photographers — they got a picture of her kissing a married man in a Mini Cooper."

Lohan even poked fun at herself. According to TMZ, sources inside the show reveal that she freely cracked jokes like, "I've been on a 90-day court ordered vacation."

According to TMZ, Lohan is currently traveling with a sober coach and removing all alcohol from everywhere she stays.
