Beyonce has spoken in detail about her miscarriage for an upcoming HBO documentary called "Life is But a Dream," according to reports.
In the new documentary the "Single Ladies" singer reveals the torment she went through two years ago when she suffered a miscarriage, sparking one of the most difficult times in her life.
"About two years ago, I was pregnant for the first time," Beyonce says in the documentary, which is set to be broadcast on Feb. 16. "And I heard the heartbeat, which was the most beautiful music I ever heard in my life."
The singer also explained how she had even pictured her child, and was choosing names prior to the heart-breaking news of the miscarriage.
She explained, "I picked out names. I envisioned what my child would look like . . . I was feeling very maternal."
Beyonce had the miscarriage quite early on in the pregnancy, when she went in for a check up and no heartbeat was found.
She reveals, "I flew back to New York to get my check up -- and no heartbeat. Literally the week before I went to the doctor, everything was fine, but there was no heartbeat."
The singer, who is married to rapper Jay-Z, got through the difficult time the only way she knows how, and that is by turning to her music.
She said, "I went into the studio and wrote the saddest song I've ever written in my life. And it was actually the first song I wrote for my album. And it was the best form of therapy for me, because it was the saddest thing I've ever been through."
However, she did not reveal which song she specifically was talking about.
Beyonce and husband Jay-Z went on to have daughter Blue Ivy in January 2012, although she admits that she was much more hesitant to reveal to people she was pregnant the second time around.
She explained, "Being pregnant was very much like falling in love. You are so open. You are so overjoyed. There's no words that can express having a baby growing inside of you, so of course you want to scream it out and tell everyone."
