Youtube! Beyonce Knowles “Upskirt Moment” for her first time concert

It's been nine months since Beyonce last performed for her adoring fans.

Taking to the stage in New Jersey last night for the first time since giving birth to daughter Blue Ivy, it appeared her time out for motherhood hasn't affected her stage presence.

Showing off her post-baby curves in a showgirl-style, fringed bralet and tiny shorts, the 30-year-old wowed the sold-out crowd on the first of a three-night stint at the Revel Resort & Casino in Atlantic City.
