Lindsay Lohan Is Quiet as a Mouse in Sneak Peek of Oprah Interview

Lindsay Lohan is ready to talk ... but in a sneak peek of her much-buzzed-about interview with Oprah Winfrey, she doesn't utter a word.

A promo clip of the sit-down, which will air Sunday, August 18, as part of "Oprah's Next Chapter" series on OWN, has been released and it's a big tease. The 27-year-old, who left rehab last Tuesday, looks glam in a bright orange dress, minimal makeup, and her straightened hair pulled into a tight ponytail. However, we don't even hear her voice.

"Are you an addict?" asks Winfrey, who is an expert at asking the tough questions.

Winfrey is then heard asking, "What does it feel like to be both an adjective and a verb for child-star-gone-wrong?"

While Lohan is just seen sitting silently batting her expertly made-up lashes in the 15-second spot, she will have the floor — and apparently have to tackle the tough questions — when the interview airs later this month.
