TV mogul Oprah Winfrey let the cameras shoot her in the bathtub and sans make-up for the last, 25th season of her chat show, which starts Sunday on her own new television station, the Oprah Winfrey Network (OWN).
Winfrey has also been caught on camera when she is "so drugged" on painkillers after an operation that she "couldn't even stand up", reports dailymail.co.uk.
The 56-year-old has called it "an uncensored look into the private world of our show", run by the "hardest working people in television - in showiness, in fact".
"Documentary film crew will capture the real life drama of ending a show that's really been our lives," she added.
The first thing in the video shows Winfrey being driven away from her home in Chicago to a nearby park in the morning for a run with her dog.
She is excited about the launch of OWN, and the last season of her chat show.
"It feels very electrifying, it feels very exciting. It's going to be bittersweet of course but it's going to be good."
