Beyoncé nervous about Atlantic City comeback

Beyoncé will be performing for the first time since birthing her daughter, Blue Ivy, this weekend at Atlantic City's Revel Resort.

The pop star admits to being nervous about performing post baby bump.

"It's a little strange, but it's important that you don't lose yourself and you still have your own passions," she says in a behind the scenes video. "And I'm back to work, I'm back to business."
