Nicole Kidman's thigh-grazing minidress shows off her amazing post-baby figure

Dressed in a thigh-grazing minidress, the actress made sure all eyes were on her as she arrived at the awards ceremony at the Royal Festival Hall.

Eschewing her usual floor-length glamour number for a fitted black shift with a gem-encrusted neckline, the actress cosied up to her singer husband, Keith Urban as they posed for pictures at the event.

Nicole Kidman, 41, made her first official appearance since giving birth to her daughter Sunday Rose in July.

Miss Kidman has spent the last three weeks in London with her husband Keith Urban and her daughter.

The Oscar-winning actress elected not to walk down the red carpet in front of fans but instead went on stage to present the award for Best Musical to summer hit Mamma Mia.

Her shoes, also by the designer, were especially made for the occasion.
