Beyonce has spoken about the miscarriage she suffered two years and said it was the “saddest thing” she’d ever gone through.

The “Single Ladies” singer, 32, is now the proud mother to daughter Blue Ivy. Shortly after the baby’s birth in January 2012, Bey’s husband, rapper Jay-Z, released “Glory,” a song celebrating Blue’s arrival.

But the tune also unleashed the some painful revelation that the couple struggled for years to get pregnant and apparently suffered at least one miscarriage. Posting the song on his website Life and Times, the Grammy Award-winning — real name Shawn Carter — raps on the track:

“The most amazing feeling I feel, words can’t describe what I’m feeling for real / Baby, I paint the sky blue, my greatest creation was you. You’re the child of destiny / You’re the child of my destiny / you’re my child with the child from Destiny’s Child/ Last time the miscarriage was tragic / We was afraid you’d disappear but nah baby you’re magic…”

Ever private, Beyonce has remained mum on the baby loss. But in her new documentary, Life is But a Dream, airing Feb. 16, on HBO, the pop powerhouse is candid about her personal tragedy.

“About two years ago, I was pregnant for the first time. 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. 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.”

It turns out Beyonce used the miscarriage as inspiration for “the saddest song” she’s ever written, though she doesn’t name the song.

“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.”
