Beyonce Debuts "Life Is But A Dream" Documentary in the Big Apple

Dialing up the glamour to promote her HBO documentary, Beyonce Knowles arrived at the Zigfield Theater for the "Life is But a Dream" premiere in New York City on Tuesday (February 12).

The "Run the World" singer dazzled in a sparkling sleeveless gown with a sheer center cutaway as she waved at fans and photographers before heading inside.

Co-directed by Mrs. Carter herself, the autobiographical documentary shares home movies of her and her sisters in their childhood, video diary entries, and behind-the-scenes footage of her performances.

The 90 minute program airs Saturday, February 16th at 9:00pm ET on HBO. In other Bey news, the 31-year-old mother of Blue Ivy recently spoke about how her baby girl has changed her in Vogue magazine, saying, "I feel like I have something that has grounded me so much more."
