Beyonce sonogram: Photo, video surface online

Beyonce’s sonogram of baby Blue Ivy has surfaced online ahead of her upcoming HBO documentary.

The 3-second video, shown in the :46 second mark in the video below, is one of several intimate highlights from the documentary “Life is But a Dream.”

Blue Ivy, who turn 1-year-old last week, is an often-discussed topic during the documentary. Beyonce also talks about her struggles to hide the pregnancy from the media and living a life outside the limelight.

“They keep putting me in these tight clothes and trying to hide it,” Beyonce says in the documentary preview. “It’s very difficult. I don’t know how I’m going to get through this.”

The documentary, directed and produced by Beyonce, is scheduled to air Feb. 16 on HBO.
