Taylor Swift was a double winner at the CMT Music Awards this week, but her performance of 'Pour Some Sugar on Me' with Def Leppard didn't win everyone over.

According to Def Leppard lead singer Joe Elliott, while the live audience seemed to enjoy the collaboration, he was puzzled by critics who described Taylor's delivery of the song's first line as "breathless."

"What a lot of people don't know is she was up for five awards," Elliott tells Rolling Stone. "And about a minute before we started that song, she had just picked up an award. So, after she accepted the award, she had to run down the stairs, run back to her dressing room and change her clothes."

Maybe Dierks Bentley wasn't our Best Dressed pick at the CMT Awards, but he was certainly the best accessorized! Dierks' wife Cassidy stayed home with their baby daughter on Tuesday night, so the country star brought the other love of his life as his date: his dog Jake.

Taylor Swift made her gangsta debut Tuesday night at the CMT Awards in this hilarious video with rap superstar T-Pain.

Brad Paisley has three new trophies on his mantel, leading the pack in CMT Award wins Tuesday night. The country superstar took home Male Video of the Year for 'Waitin' on a Woman,' CMT Performance of the Year for 'Country Boy' (with Alan Jackson, George Strait and Dierks Bentley) and Collaborative Video of the Year for 'Start a Band' with Keith Urban.

Taylor Swift leads the ladies with two CMT wins: Video of the Year and Female Video of the Year for 'Love Story.' The 19-year-old superstar opened the show in a hilarious segment, in which she made a cameo in the 'Star Trek' movie, played with the Tennessee Titans and rapped with T-Pain. She also performed her latest hit, 'You Belong With Me,' and a duet of 'Pour Some Sugar On Me' with Def Leppard.

The CMT Awards were filled with surprise performances by artists you might not normally see around Nashville. Rapper T-Pain performed a hilarious rap collaboration with Taylor Swift in the show's opening number. Taylor also performed with her rock heroes, Def Leppard, singing their classic hit 'Pour Some Sugar On Me.' And the most surprising guests of the evening perhaps, were the B-52's, who took the stage with CMT Duo Video of the Year winner Sugarland, performing their 1989 hit, 'Love Shack.' Sugarland's Jennifer Nettles and Kristian Bush say they've loved the song for decades. They even covered it for their upcoming 'Live On the Inside' live DVD.

Taylor Swift's 'Love Story' is CMT's Video of the Year, the night's top honor at the annual CMT Awards.

"Thank you so much," Taylor gushed upon accepting the final award of the night. "I wanna thank CMT for letting me win so many of my dreams this year. I got to sing with my heroes Def Leppard. I love you guys so much!"

Taylor also expressed her appreciation for a couple of her role models. "I want to thank Shania Twain for making such theatrical videos, and I want to thank Garth Brooks for always putting his fans first. I take my cues from you. Also I want to thank my little brother Austin for agreeing to be my date tonight. And I want to thank the fans for giving me Video of the Year. My whole family is here watching. Thank you!"

Friends on and off stage, Brad Paisley and Keith Urban took home the award for Collaborative Video of the Year for their hit single, 'Start a Band'.

"Brad called me up and he said he had a song he wanted me to play on," Keith said." I said absolutely. It was a blast."

"First of all, Martina is shorter than I thought," Brad joked of his labelmate Martina McBride. "What an honor to work with this guy (Keith). I think the world of you, and everybody here does, too."
