Julianne Hough shows off dancers legs in crimson sequined number with thigh-high split as Gabrielle Union dazzles on America's Got Talent red carpet

It was a night to celebrate the best and brightest of undiscovered talent, and the judges dressed brightly in kind.

America's Got Talent celebrity judges Julianne Hough and Gabrielle Union in turn gave showy displays of their shapely legs and arms in their sequinned gowns for Tuesday's show, which unveiled the first round of live finals in Los Angeles, California.

Julianne was a vision in glitzy red sparkles, in a floor-length sequinned gown with a delightful heart-shaped cutout over the chest and a sky-high thigh split.

The 31-year-old Footloose star wore matching red open-toed Mary Janes, and sported bright red lipstick and a sleek blond bob for the evening.

The sleeves on Julianne's high-necked dress were roomy and long.

Union, for her part, went sleeveless in a sequinned black jumpsuit, accented with a phenomenal ruffled white frill effect over one shoulder.

Gabrielle, 46, wore her hair in an elegant high top knot and matched the wow factor of her outfit with an equally impressive dark manicure.

The sparkle and shine continued with Lauren Silverman, who arrived with her typically dressed-down partner Simon Cowell in a bright gold metallic animal print turtleneck dress.

Lauren's wrap gown had an asymmetrical hem that fell to her mid-calf, and opened at her thigh.

Silverman took the opportunity to plant a big kiss on a wide-eyed Cowell in front of the cameras.
