Before HBO premiered her HBO documentary, Beyoncé: Life Is But a Dream, the singer sat down with Oprah Winfrey for a candid interview for "Oprah's Next Chapter."
During the one-hour episode, Beyonce opened up about her Super Bowl performance, saying it was one of the hardest performances in her life; her publicized split with father/manager Mathew Knowles in business; and her relationship with husband Jay-Z.
Later, she reflected on experiencing a miscarriage, and later, giving birth to her daughter, Blue Ivy.
