Oprah Winfrey has finally revealed why she has never married longtime boyfriend Stedman Graham – because she didn't want to.

The talk-show host, 56, makes the revelation in the 10th anniversary edition of her magazine, O.

In a special interview with a handful of readers, she was asked how she feels about never having married.

Winfrey replied: "Actually, Stedman asked me to marry him and, at first, I said yes. But it turned out that I wanted to be asked to be married more than I wanted to be married.”

Winfrey revealed that Graham proposed to her 17 years ago in 1993 – the same year that she announced she was to write her autobiography in time for her 40th birthday.

In the end, she decided to do neither.

She said: "Everybody was going to give me a… [bridal] shower. And I was saying, 'I don't want this, I don't want this'… It just felt like the wrong thing for me.

“This was at the same time I was supposed to have the book coming out… 14 September or something, and our wedding had been scheduled for 8 September. We had a date and everything.”

She added: "So Stedman says, 'Well, I don't want to have my wedding in competition with your book'. And I remember thinking, 'Yes! Really? OK, great!'

"I ended up cancelling both and we have never discussed it since that day."
