Oprah Winfrey sits down with singer Robin Thicke on an all-new episode of Oprah's Next Chapter, airing Sunday, Oct.13.

In the candid interview, Oprah and Robin discuss the year’s #1 summer hit Blurred Lines, his VMA performance with Miley Cyrus and his high-profile marriage to actress Paula Patton.

Opening up about the 2013 VMAs -- in which Miley Cyrus stripped down to a nude-colored PVC bikini -- Thicke believes the controversy was "silly."

 "Well, I was on stage. I didn't see it, you know, so to me I'm walking out towards Miley. I'm not thinking sex. I'm thinking fun, you know?" he told Oprah.

"I mean her and I don't have that kind of --" he said before Oprah interrupted, "But she's twerking up against your cojones."

Thicke brushed off the raunchy performance. "I'm singing my butt off so I'm sitting there. I'm looking up at this guy and I'm singing. I'm not really paying attention to all that. That's on her. I'm like people ask me, you know, do you twerk? I go, listen, I'm the twerkee. I'm twerked upon. I don't twerk myself, okay? I'm just twerked upon."

Opening up about his music video for Blurred Lines, Thicke reveals his wife played a huge part in creating the storyline.

"[She is] my muse. It was no different when this happened. I told her the idea. She immediately started grabbing all these magazines and coming up with images and ideas that we used in the video. So that's just who she is. Of course once you see the video back and you see your husband romping around with three topless girls, you know, there's gonna be some jealousy, the same way I get jealous if she's doing a love scene or something," he said.

Next, Oprah asked how he and Patton have remained together for over 20 years despite being in Hollywood.

"So how have you made that work in this world in this culture in Hollywood?" Oprah asked.

"You know, like I said, it's -- you pretty much take it one day at a time. The one thing I've realized about loving somebody is you have to love them every day. Like people think, oh, I'll get to loving you on Saturday. Or I'll get to -- I don't have time this week. I don't -- and the thing is that people are changing every day. Their thoughts. Their desires. Their insecurities change every day," Thicke said.

In a recent interview, Thicke had described his marriage as most functional dysfunctional marriage. "What does that mean?" Oprah asked.

"Just meaning that we're no different than any couple out there. And we have our fights. We have our -- our problems. But somehow there is this big bang theory that just pulls us close to each other and we are madly in love and can't quit each other," Thicke responded.
