Jennifer Hudson onstage in leather

Jennifer Hudson graced the stage of The Masterpass House in Miami Beach on Saturday night.

The Oscar-winning 35-year-old had worn a short-sleeved black top that hugged her enviably svelte figure, tucking it into a tiny black miniskirt.

She got in a bit of posing offstage, placing her hand at her trim waistline and showing off her smashing legs as she balanced on ankle-strap heels.

The evening's event was for Stand Up To Cancer, a celebrity-flypaper charity program that was started by way of the Entertainment Industry Foundation.

While offstage, JHud also stood for the cameras whilst flanked by Major League Baseball Commissioner Robert Manfred and his wife Colleen Manfred.

Jennifer, fresh off coaching and winning the sixth season of The Voice UK, was unveiled this May as a coach on the next season of NBC's The Voice.
