Beyoncé and Sasha Fierce are two very different people.
In a new teaser for her upcoming HBO documentary, Jay-Z's wife reveals her struggle with balancing her professional and private life.
"I always battle with 'How much do I reveal about myself?'" the 31-year-old singer-actress says in a voiceover played over the 25-second clip. Shots of the Dreamgirls star performing on stage are cut together with homemade videos. "If I'm scared, be scared. Allow it. Release it."
One quick cut even shows Beyoncé's bare baby bump during the early stages of her pregnancy with Blue Ivy Carter.
The feature-length film, which is also directed by Bey, premieres Feb. 16 on HBO. That's not the only date to mark on the calendar, though: Hov himself celebrates his 43rd birthday Tuesday.
Gotta keep up with those Carters!
