The 46th Annual Academy of Country Music Awards took place Sunday April 3 in Las Vegas.

The awards show was full of A-list celebrities. Along with cowboy hats and boots, the night was filled with doses of glam and rock and roll.

Some of the highlights included American Idol judge Steven Tyler performing alongside former American Idol contestant Carrie Underwood on her hit Undo It. The pair also sang Aerosmith's Walk This way.

Miranda Lambert was a big winner as she took home four awards, including Best Female Vocalist as well as Single, Song and Video of the Year for her tune The House That Built Me.  Another big winner of the night was 21-year-old Taylor Swift who took home the fan-voted award for Entertainer of the Year.

She is the youngest-ever winner of that honor. Lady Antebellum, who had a big night a few months ago at the Grammy Awards, took home to award for Top Vocal Group and Album of the Year for Need You Now. Here are photos of some of the night's biggest highlights.
