Carrie Underwood Stuns in Two Sheer Gowns on 'American Idol' Finale

Showing off those long legs!

Carrie Underwood stunned in back-to-back see-through gowns for the finale of American Idol on Thursday, April 7.

First, the “Before He Cheats” singer, 33, dazzled on the red carpet wearing a sultry black gown by Yanina Couture. The sizzling ensemble featured a plunging neckline, a peplum detail, and hundreds of feather-like appliqués. Underwood paired the smoldering look with a bevy of cocktail rings and statement earrings.

But that wasn’t the only time the American Idol alum showed off her toned gams for the final episode of Fox’s reality competition. For her performance of “Something in the Water,” Underwood also opted for a sheer skirt.

The sleeveless sky-blue Monique Lhuillier design was embellished with cascading beads, and Underwood rocked the look with a metallic silver belt and Anne Sisteron jewelry.

On both occasions the mom of Isaiah, 13 months, wore her blond bob in a sleek straight style, and added a sexy touch to her look with an edgy smoky eye.

“I can’t believe I’m here at the @AmericanIdol farewell. It’s been an incredible run!” the Storyteller singer wrote via Twitter. “Thank you for season 4! I know I’m gonna cry tonight … “
