Okay, before we get to the night's big winners, let's get to the good stuff from Wednesday's fan-voted 2011 CMT Music Awards.

First, Shania Twain fell down and went boom.

On her way out to present the big buckle for Male Video of the Year, Twain slipped and fell right on her rear end. The total pro popped back up, mouthed "I'm okay" and the show did go on.

Maybe she was shocked by the undies being thrown onstage at Kid Rock as he introduced her?

Speaking of undies, Sheryl Crow's almost stole the show.

Crow wore a short, white skirt and sat on a stool to sing "Collide" alongside host Kid Rock. She briefly flashed the camera as she stood up.

It happened in a blink of the eye, but in the age of DVRs, the moment went viral on Twitter, something Crow acknowledged about an hour later when she and Sara Evans presented an award.

"Well, at least you were wearing underwear," Evans told Crow.

"I was wearing underwear because I'm good, clean, wholesome family fun," Crow joked.

The night's other big shocker? Justin Bieber won a CMT award, taking home a belt buckle for best collaboration with Rascal Flatts on "That Should Be Me."

Yes, that Justin Bieber.

Very strange.

Now to the other stuff.

Taylor Swift won the night's biggest award, video of the year, for her song "Mine." Lambert took female video of the year for "The House That Built Me," the life-changing song that's earned her a Grammy and the major country awards already. And Lambert's new husband, Blake Shelton, was the night's only multiple winner.

Swift, who won the fan-voted entertainer of the year award at the Academy of Country Music Awards earlier this year, joined the show via live video uplink from Wisconsin where she's on tour.

"I wish I could be there, but I'm hanging out with 15,000 of my closest friends in Milwaukee," Swift said as frenzied fans screamed in the background.

Shelton and Lambert also weren't able to make it.

Swift did join Shania Twain for their pre-recorded faux movie trailer recreating "Thelma & Louise" that included guest appearances by Donald Trump and Kenny Rogers. Justin Bieber induced tears from teenagers as he walked the red carpet with Rascal Flatts. Pittsburgh Steelers wide receiver and "Dancing With the Stars" champion Hines Ward wore cowboy boots and shook his hips on stage.

Lady A turned in one of the night's most interesting performances. The trio opened with its record-setting single "Just a Kiss" before singer Charles Kelley jumped on the drums as the band morphed into Prince's "Kiss."

Wynonna Judd put Kid Rock in his place and taught him a little something about country on a duet of his "Hell, Yes, I'm Country."

Jason Aldean, who was shut out after earning a leading four nominations, topped off the night with a surprise version of his hip hop-infused hit "Dirt Road Anthem" with rapper Ludacris. It was a perfect end to a show that thrived on unlikely pairings.

Kid Rock, hosting for the second year, thought the song was a great illustration of where country is going.

"I've said this before: Country and hip hop aren't that far apart in spirit if you break it down," he said after the show. "They're both blues music."

Shelton, who appeared via video uplink from the set of his reality contest show "The Voice," won male video of the year for "Who Are You When I'm Not Looking" and best Web video for "Kiss My Country Ass." Sugarland kicked off the night with the first win, taking duo video of the year for "Stuck Like Glue."

Lady Antebellum won group video of the year for "Hello World." The Band Perry won breakthrough video for "If I Die Young." Jimmy Buffett and Zac Brown won best CMT performance of the year for "Margaritaville."
