Jason Aldean and Chris Stapleton Are the Big Winners at ACM Awards

All the highlights from last night's show!

— -- It was Little Big Town's Kimberly Schlapman who said it best at the 51st Annual Academy of Country Music Awards as she accepted the Vocal Group of the Year trophy: "Thanks, Chris Stapleton, for not being a vocal group!"

That category was one of the few Stapleton didn't win last night in Las Vegas.

In a repeat of his sweep of the CMA Awards in November, Stapleton scooped the trophies for Male Vocalist of the Year, New Male Vocalist of the Year, Album of the Year for "Traveller" and Song of the Year for "Nobody to Blame."

When Bryan asked who else in the audience wanted to take credit for Stapleton's success, the entire arena got to its collective feet.

This was Bentley's first year co-hosting the ACMs after years of "Bluke" -- the team of Blake Shelton and Luke Bryan. In fact, Shelton showed up unexpectedly to duet with Bryan on the night's first song and then wished the new duo of "Lierks" luck.

"Holy crap!" he exclaimed, wiping his mouth. "My heart is beating a million miles a minute and I have lipstick on my lips from kissing my beautiful wife!"

Meanwhile, Jason Aldean won ACM's biggest prize -- Entertainer of the Year -- which he'd never won before. "I was just starting to think this wasn't in the cards for me," he said, adding, "I may be rough around the edges a little bit, but I love this business, I love the people in it and I love the fans that support it...this has been one of the best nights of my professional career."

As usual, though, the ACMs weren't so much about the actual awards as they were about the performances: there were 22 musical performances in all. Many artists used the show as an opportunity to debut new material, such as Kenny Chesney with his new track "Noise," Jason Aldean with "When the Lights Come On," Charles Kelley with "Lonely Girl" and Carrie Underwood with "Church Bells."
