Beyonce Bashes Surrogacy Rumors Surrounding Baby Blue Ivy Pregnancy in New Documentary, 'I'm Not that Vain' [VIDEO]

In an upcoming HBO documentary on the life of pop megastar Beyonce entitled "Life is But a Dream," the 31-year-old songstress not only opens up about the heartbreak involving her tragic miscarriage two years ago, but also heatedly denies the "conspiracy theories" surrounding her successful pregnancy with baby Blue Ivy. Beyonce bashes rumors that she used a surrogate, and insists that she conceived Blue Ivy naturally with husband Jay-Z. The Super Bowl halftime performer claims that she would never be so vain to take advantage of such a rewarding experience as giving birth... especially after going through such a sad and unfortunate miscarriage.

Beyonce gets very personal in "Life is But a Dream" (which premieres on HBO on Feb. 16), and even discusses the surrogacy rumors surrounding baby Blue Ivy's January, 2012 birth. Some harsh conspiracy theorists went so far as to claim that the Destiny's Child starlet wore a false baby bump in the nine months leading up to her baby's birth. According to Beyonce, that's just sad and ridiculous:

 "To think that I would be that vain," the Grammy Award winner says in her new documentary. "I respect mothers and women so much. 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."

Beyonce insists that she would never fake something as serious as pregnancy, especially on the heels of such a devastating miscarriage (which the songstress considers the "saddest thing I've ever been through" - read more on that full story here).

Beyonce goes on to explain the miracle of childbirth, and why it's not something to mess around with:

"It's the most powerful thing you can do in your life -- and especially after losing a child, the pain and trauma from that just makes it mean that much more . . . A child, you don't play around with that... My baby was born out of a conflict in my life and that struggle had to be settled. I wouldn't have gone through the pain if I hadn't gone down the path. There's something so relieving about life taking over you like that. You're playing a part in a much bigger show and that's what life is, it's the greatest show on earth . . . I felt like god was giving me a chance to assist in a miracle."
