WATCH: Beyonce's 'Life Is But A Dream' trailer

HBO has unveiled the latest trailer for Beyonce's self-directed documentary, "Life Is But A Dream," a personal look at the life of a star trying to live up to expectations while staying grounded. This version of the trailer features more clips of Beyonce staring thoughtfully into her laptop camera, a longer glimpse of her baby bump and ultrasound footage of Blue Ivy in the womb.

"I always battle with how much do I reveal about myself," Bey says in the trailer. "How do I stay current? How do I stay soulful?"

"Power's not given to you, you have to take it," the 31-year-old singer muses. "You're playing a part in a much bigger show. That's what life is."

"Life Is But a Dream" premieres February 16 on HBO at 9p.m.
