ACM

In a surprise upset, Luke Bryan took home the coveted Entertainer of the Year award at the 2013 Academy of Country Music Awards on Sunday night (April 7) -- beating out more established stars like Miranda Lambert, Blake Shelton and Taylor Swift.

Keith Urban presented the Female Vocalist of the Year award to the dazzling Miranda Lambert at the 2013 ACMs, and she was completely surprised by the win. "I thought for sure Carrie had it this year, and she damn well deserves it!" she said as she took the stage... and broke into tears.

Mega superstars Garth Brooks and George Strait gave a once-in-a-lifetime performance at the 2013 ACMs on Sunday night (April 7), singing together for the first time ever in tribute to Dick Clark.

After taking home awards for Vocal Group of the Year and Video of the Year earlier in the evening, country foursome Little Big Town took the stage at the 48th Annual ACM Awards with their new single 'Your Side of the Bed.'

Tim McGraw performed 'Highway Don't Care' at the 2013 Academy of Country Music awards on Sunday night (April 7), and a couple of high-powered friends dropped in to help him out.

Little Big Town took home the 2013 ACM Award for Vocal Group of the Year. It was a breakout past 12 months for the troupe, thanks to their smash hit 'Pontoon.' They've been doing their thing for so long and thanks to their monstrous, breakthrough year, this award was well-deserved and equally as hard-earned.

Eric Church took another step away from being a Nashville outsider to being the new mainstream of Music City by winning Album of the Year at the 2013 ACM Awards on Sunday night (April 7), beating such huge acts as Carrie Underwood, Taylor Swift, Luke Bryan and Little Big Town.

All-star collaborations were the order early during the 2013 ACM Awards performances in Las Vegas on Sunday night (April 7). Even Eric Church's acoustic performance of 'Like Jesus Does' turned into a duet. Blake Shelton, Sheryl Crow, Luke Bryan and Pistol Annies began the show performing 'Boys 'Round Here.' It was an electric introduction to country music's biggest party.

George Strait performed his current single 'Give It All We Got Tonight' at the 2013 ACM Awards show on Sunday (April 7). The superstar is planning to release a new album later this year, and is currently on his farewell tour. Despite some audio difficulties, the crowd at the MGM Grand in Las Vegas still gave the King a healthy round of applause.

The big 2013 ACM Awards winners in Las Vegas were Miranda Lambert and Luke Bryan. Lambert took home three trophies, including Female Vocalist of the Year and Single and Song of the Year for 'Over You.' The singer couldn't help but become emotional as she accepted her fifth straight Female Vocalist trophy.

The 2013 Academy of Country Music Awards will air live on Sunday night (April 7) from Las Vegas. The annual awards show features a lineup that's a veritable Who's Who of contemporary country, but this year there's going to be one notable absence: Justin Moore. The singer skipped out on Vegas a day early to keep another, more important commitment.

There is a happy ending to this story! Last year, New Jersey teen Kevin McGuire, who was suffering from cancer and in need of a bone marrow transplant, asked Taylor Swift to prom via a Facebook campaign. Despite everyone's best efforts, things didn't work out as planned. Luckily for McGuire, he's getting a second chance in more ways than one!

The Academy of Country Music Awards telecast on Sunday night (April 7) is shaping up to be quite an event. In addition to all of the great live acts already announced, pop musician John Mayer has been added to the lineup, joining Brad Paisley for a joint performance on the show.

The 2013 ACM Awards are just days away, and while the country music industry is anxiously awaiting to see who wins the big awards, fans are looking forward to the performances, surprise collaborations and unexpected moments of brilliance. These potential moments could prove to be the ones fans are talking about come Monday.

The Academy of Country Music has announced performers for the free and open-to-the-public 2013 ACM Experience, which is taking place during 'The Week Vegas Goes Country' leading up to the 48th Annual Country Music Awards. This year, the musical acts include Jewel and Easton Corbin.

Luke Bryan is bigger than ever, with four ACM Awards nominations and a super successful Dirt Road Diaries Tour, but even the biggest stars have a case of nerves. In fact, when he was asked to step into the iconic Reba McEntire's shoes of co-hosting the ACMs, he almost turned down the offer.
