Oprah Winfrey believes there has never been a "star" like Justin Bieber.
The chat-show host has revealed a clip from her upcoming interview with the award-winning pop sensation on 'Oprah's Next Chapter', in which she discusses his rise to fame and compares his "screaming fans" to those of legendary musicians such as Michael Jackson.
After referring to the similarities between this interview and her chat with the 'Thriller' hitmaker in 1993 she says: "Justin Bieber is a phenomenon for our time and just like Elvis Presley; just like the Beatles and also like Michael Jackson he has millions of screaming fans all over the world. He's adored by them."
The clip then shows a teaser of Oprah and Justin sat together, with Oprah telling him: "There's never been a star like you. Do you realise that?" to which the 18-year-old singer responds: "What do you mean by that?"
She then proceeds to talk about how Justin is a "product" of social media websites like twitter, which helped boost his international success, as well as reminiscing about when she use to obsess over Sir Paul McCartney.
She says: "Obviously lots of people compare your audiences to Michael Jackson's audiences - the screaming fans and your audience's to the Beatles fans.
"I mean when I saw the crowd last night it reminded me of myself and Paul McCartney, you know?
"But even those tremendous legends who really changed the face of music for our culture did not have a start-up like yours because you are a product of, to a great extent, social media. So therefore there's never been a star like you."
The full interview on 'Oprah's Next Chapter' will air on 'OWN' on Sunday November 25 at 9pm EST.
