NEW YORK (February 13, 2013)--Oprah Winfrey made a surprise appearance Tuesday night at the premiere of Beyonce's HBO documentary, 'Life is But a Dream,' posed with the star and spoke of the candor the singer showed in making it.

The film takes a no-holds-barred look at moments in the 31-year old singer's life, including her miscarriage, reports of faking her pregnancy, and firing her father as her manager.

While the revelations Beyonce makes about herself in the film are comparable to the results Winfrey usually gets from her tough style of interviewing, the talk show host had kudos for the singer.

Winfrey said Beyonce did a "much better job" of telling her own story.

"I wouldn't have been in the bedroom and in the closet and in the car and on vacation," she said.
