Video: 'Raw' Beyonce 'revealed' in HBO documentary

"Raw. Real. Revealed."

That's what Beyonce is promising in the just-released trailer for her HBO documentary.

Flashes of the superstar zoom by, including one of her hugging hubby Jay-Z, a shot of her pregnant belly and other behind-the-scenes and personal shots.

"I always battle with 'How much do I reveal about myself?' " Beyoncé, 31, says in voiceover.

When HBO and Beyonce announced the project, she said she would be covering her childhood, early stages as an entrepreneur, concert prep and her return to the spotlight after the birth of daughter Blue Ivy Carter in January.

The feature-length film doc is slated to air Feb. 16.
