Information surrounding Beyonce's next album continues to trickle out following The-Dream's proclamation last December that we'd hear new music from her prior to her performance at the Super Bowl. At this point, that seems unlikely, but we have learned that one of the album's songs is the saddest one she has written to date.

According to Us Weekly, the track deals with the miscarriage she suffered two years ago, which her husband, Jay-Z, previously addressed in his song dedicated to their daughter, Blue Ivy Carter. The following quote is from her upcoming Life Is But A Dream documentary, which airs February 16 on HBO:

"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."

You can watch the trailer for the documentary here. Bey will perform during the half-time show at the Super Bowl on Sunday, February 3.
