While Beyoncé is now the proud parent of adorable daughter Blue Ivy, motherhood wasn't the easiest road for Jay-Z's wife to travel.
And now, the Super Bowl singer is opening up about the miscarriage she suffered, which was revealed last year by her rapping hubby in the track "Glory."
But B herself has never addressed the experience—until now, that is.
"And I heard the heartbeat, which was the most beautiful music I ever heard in my life."
While she does not detail when, exactly, she suffered her loss, she did say that she felt it hard.
"I picked out names. I envisioned what my child would look like...I was feeling very maternal," she said, adding that something went wrong early in the pregnancy, which she only found out during a routine doctor's appointment.
"I flew back to New York to get my checkup—and no heartbeat. Literally the week before I went to the doctor, everything was fine, but there was no heartbeat."
And she dealt with the loss the best way she knew how.
"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," she said, albeit not naming the track or even if it made the final cut. "And it was the best form of therapy for me, because it was the saddest thing I've ever been through."
Of course, her story has the happiest of endings, as she and Jay welcomed their daughter on Jan. 7, 2011.
