Red carpet was rolled outside the Mandalay Bay Events Center in Las Vegas to welcome celebrity guests of the 2013 American Country Awards on Tuesday, December 10. Dressing their best to the event, Kellie Pickler and Jewel Kilcher were among the stars who turned heads as they posed for photographers before entering the venue.

"American Idol" alumna Pickler showed some skin in a long turquoise dress that had a plunging neckline. She wore her blonde hair in soft curls and applied a shimmery pink eyeshadow that matched her glittery gown.

Jewel also looked sexy in a black little dress by Jovani, paired with Rupert Sanderson shoes, Nancy Gonzalez shoes and Jacob & Co. jewelry. She was all smiles as she posed with Sheryl Crow, who rocked a hot pink dress.

LeAnn Rimes opted for a conventional but glamorous style with a Reem Acra dress. Her hair was pulled back into a ponytail as she kept her lips neutral. She was joined by her husband Eddie Cibrian, who looked sharp in a suit.

Danica Patrick, who was tapped to co-host the event with Trace Adkins, stunned in a silver dress. Adkins, meanwhile, went all black that night as her wife Rhonda Forlaw who came to support him wore a matching black number.

Another former "Idol" contestant Lauren Alaina was red hot in a Jovani dress. She pulled back her platinum hair into a fun updo. Hillary Scott of Lady Antebellum, meanwhile, showed off her post-baby body in a blue printed dress.

In the male department, Luke Bryan wore a black suit without a tie as her wife Caroline Boyer donned a white long dress. Scotty McCreery went casual with a checkered shirt topped with a black jacket, while Lady Antebellum's Dave Haywood and Charles Kelley looked gorgeous in black outfits.
