Beyonce may be one of the most private and guarded pop stars in the world. Obviously, you know Bey isn’t going to getting caught up in Twitter beefs or other senseless social media nonsense. And, when it comes to matters of her personal life, the details always remain under wraps. But that looks like that will change when her HBO documentary debuts on Feb 16. US Weekly just revealed some exclusive quotes from Beyonce talking about her miscarriage for the first time. Jay briefly touched on the subject on his dedication track to his first born daughter Blue Ivy, but Bey remained silent about the tragedy throughout 2012.

In a surprising moment of candor, she opens up for the first time about the incident and its aftermath in Life Is But a Dream, her new documentary debuting on HBO in February. “About two years ago, I was pregnant for the first time,” the Grammy winner says in one scene. “And I heard the heartbeat, which was the most beautiful music I ever heard in my life.”

“I picked out names,” Beyonce recalls. “I envisioned what my child would look like . . . I was feeling very maternal.”

But something went wrong in the early stages, the “Love on Top” singer reveals. “I flew back to New York to get my check up — and no heartbeat,” she says. “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 doesn’t name the track. “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.”

All of which made her successful pregnancy with Blue Ivy all the more exciting and joyful. “Being pregnant was very much like falling in love,” she muse. “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.”
