Beyonce: She's just like us! The "Love On Top" singer admits that she has just as many doubts as the next person in a newly released trailer for her upcoming HBO documentary, Life Is But a Dream.

"People see celebrities and they have money and fame, but I'm a human being," she says in the voiceover. "I cry, I get scared, I get nervous just like everyone else."

In the clip, Beyonce addresses some of the internal struggles that she's undergone figuring out how much of her life to keep under wraps and how much to share with fans.

"I always battle with, how much do I reveal about myself," she says. "How do I stay current? How do I stay soulful? I felt like I had been so commercially successful, but it wasn't enough."

"There's something really stressful about having to keep up with [everything]," she continues. "[If] you can't express yourself, you can't grow. It's the battle of my life so I set a goal and my goal was independence."

Beyonce, who welcomed daughter baby Blue Ivy last year, says she found meaning through motherhood, however.

"I just had a feeling that something was going on," she confesses of her pregnancy in the video. "Really, this is crazy."

The famously private singer then flashes an image of baby Blue's sonogram, as well as footage of her pregnant belly, indirectly addressing rumors that she used a surrogate for her child.

"They keep putting me in these tight clothes and trying to hide it, it's very difficult," she of trying to hide her growing baby bump. "I don't know how I'm going to do this."

But do it she did. Beyonce and husband Jay-Z **welcomed Blue Ivy into the world last January, and have been sharing photos of their growing daughter on their respective websites ever since.
