“I always battle with how much do I reveal about myself,” she says in the trailer’s intro.
In the 85-second clip released Friday by Yahoo! Music, the superstar talks about her 2011 pregnancy that appears to be a major theme in the documentary.
“I just had a feeling that something was going on,” she says, referring to her pregnancy.
The sneak peak delves into Beyoncé’s struggle to keep news of her pregnancy a secret.
“They keep putting me in these tight clothes and trying to hide it. It’s very difficult. I don’t know how I’m going to get through this,” she says.
Clips show Beyoncé exposing her tiny baby bump and also shows an image of her ultrasound for daughter Blue Ivy, who was born Jan. 7, 2012, and recently celebrated her first birthday.
In addition, the documentary explores Beyoncé’s desire to show that she is a normal person.
“People see celebrities, and they have money and fame, but I’m a human being,” she adds. “I cry. I get scared. I get nervous just like everyone else.”
Beyoncé directs, stars in and executive-produces the film, which debuts Feb. 16 on HBO.
