In Beyonce's upcoming HBO documentary "Life Is But A Dream," she opens up on some very personal topics that she's kept fairly quiet about in the past: her miscarriage and the rumors that she used a surrogate mother to have her child.  In the documentary she calls the rumors about her using a surrogate "ridiculous" and "crazy."

Here's a preview of what you can expect Beyonce to talk about when the documentary airs on HBO:

"There's a stupid rumor. The most ridiculous rumor I think I've ever had about me. It's crazy. To think I would be that vain – I respect mothers and women so much and to be able to experience bringing a child into this world, if you're lucky and fortunate enough to experience that, I would never, ever take that for granted. It's the most powerful thing you can do. Especially after losing a child, the pain and trauma from that just makes it mean so much more to get an opportunity to bring life into the world. It seems like people should have boundaries."
