Beyoncé says she battles with how much to reveal about herself. We're not sure who won the battle, but she has an HBO documentary about her life coming out on February 16, called Life Is But a Dream.

In a sneak peek of the doc, Beyonce shows off baby Blue Ivy's sonogram and talks about how her handlers worked hard to keep her pregnancy a secret before her big reveal at the 2011 MTV VMAs. "They keep putting me in these tight clothes and trying to hide it, it's very difficult," she says in the video (watch below), showing off her baby bump. "I don't know how I'm going to do this."

Mama B will sing the National Anthem at President Obama's inauguration, and she'll perform during the Super Bowl half-time show as part of the big Destiny's Child reunion. And, rumor has it, Blue Ivy just got a Barbie worth $80K for her first birthday. This family is already living large in 2013!
