For people who know Beyonce, everyone knows how the 31-year-old who is now a mother of one, Blu Ivy Carter, is so private but she has managed to go beyond and reveal that before her one year old daughter, she had a miscarriage and it was the saddest thing she had to endure.

“About two years ago, I was pregnant for the first time,” Beyonce revealed in a preview of her up coming HBO Documentary, Life Is But a Dream. “And I heard the heartbeat, which was the most beautiful music I ever heard in my life. I picked out names. I envisioned what my child would look like.. I was feeling very maternal.”

Beyonce, who was at the time and still is married to rapper, Jay Z became pregnant about two years before getting pregnant with Blu Ivy. She lost the child in the early stages of her pregnancy. “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. I went into the studio and wrote the saddest song I’ve ever written in my life,” she says although she does not name the song. “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.”

The star’s miscarriage was first made known by her husband, Jay-Z in his track Glory, which he wrote after the birth of Blue Ivy in January 2012. The lyrics said, “Last time the miscarriage was so tragic/We was afraid you’d disappear/But nah baby you magic.”

After discovering she was pregnant, Beyonce was thrilled. “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,” she says.
