In the 90-minute exclusive, Beyoncé shared heart-warming moments about husband Jay-Z saying, "He's taught me so much about being an artist. Not a musician, but an artist. This baby has made me love him more than I thought I could ever love another human being."

Rounding out the documentary, 13-month-old Blue Ivy Carter made her grand entrance, balancing on her mother's lap.
In an interview with Oprah, Beyonce told Winfrey, "There are so many connections in the film that I didn't realize until I gave birth. Everything just completely connected and I said now I know who I am ... I wasn't complete before my daughter."
Beautiful Bey's HBO documentary, "Life is But a Dream," debuted Saturday night, in which the singer revealed details about her miscarriage, marriage and daughter Blue Ivy.
