Beyonce's documentary "Life is But a Dream" will air tonight at 9pm EST on HBO giving her fans a glimpse of the private life of the singer.

The documentary is been highly promoted online and HBO has released a trailer and previews of the movie that promise fans to learn more about the singer's career, her marriage to rapper Jay-Z, her miscarriage and her daughter Blue Ivy Carter.

Amid all the hype, on Friday, HBO leaked a photo of Beyonce holding her daughter Blue Ivy Carter.

"It is very hard for me to publicly expose my deepest emotions. I've always been very protective about my private life, so sharing my deepest moments with the world was challenging. But I wanted to say something about my perspective on life, and I hope it comes across in the film the way it is intended, in a way that is raw, artistic and sincere," Beyonce said in an interview with HBO posted on the channel's website.

The movie was directed by Beyonce and recorded with her laptop.
