Top-selling trio Lady Antebellum were the dominant winners at the Academy of Country Music Awards on Sunday, grabbing five trophies, including song and single record of the year for crossover hit Need You Now, while also snapping Rascal Flatts' seven-year run as best vocal group.

"We are having a blast tonight," singer Charles Kelly told the crowd after win No. 4. "We love you all. We will never forget this night."

Lady A came into the awards ceremony at the MGM Grand with a leading seven nominations and had won five of seven possible (they got two trophies for their single record of the year win because they also produced the record, and also got two trophies for their song of the year win because they composed Need You Now).

Carrie Underwood became the first woman to win two entertainer of the year awards; She won the coveted award last year. Also up for the fan-voted award was Taylor Swift, Kenny Chesney, Toby Keith, Brad Paisley, George Strait, Keith Urban and the Zac Brown Band.

Miranda Lambert won album of the year with Revolution. Lambert, whose Crazy Ex-Girlfriend won album of the year in 2007, also won in the video category with White Liar in awards given out Saturday night.

Lambert didn't get to say much about her win. She started to address the crowd, then stopped short to make sure producer Frank Liddell got a moment in the spotlight. But as soon as he started to issue thank yous, he was cut off and the camera panned away, eliciting boos from the crowd.

After a commercial break, she came back on stage to perform her latest single, The House That Built Me.

Lady A also could help celebrate the win of one of the night's other winners, Luke Bryan, who nabbed top new artist. Lady A's Kelley and Dave Haywood helped their good buddy write his hit, Do I.

The show, held at the MGM Grand, kicked off with Underwood and Lambert, joined on stage later by Paisley, Charlie Daniels and John Fogerty, who ripped through a rendition of Creedence Clearwater Revival's Travelin' Band.

"That's how you start a television show, son!" shouted Daniels, who recently recovered from a stroke.

The show was heavy on performances, including those by Chesney and Swift.

Swift began her performance of Change while soaring over the crowd on a platform. She ripped off her white dress and reveal a black outfit underneath, made her way through the crowd and joined the Tritones, a college co-ed a capella group on stage for a spirited chorus. She then fell backward into a crowd of fans.

Keith hit an emotional note with a performance of Cryin' For Me (Wayman's Song), dedicated to his late friend, jazz artist and former basketball star Wayman Tisdale, who died last May.

The show also had it's share of non-country celebrities, including LL Cool J, Olympic gold medalist Lindsey Vonn and Las Vegas staple Cher, who goofed when she announced that Blake Shelton had already won a CMA Award — instead of an ACM — the previous evening.
