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."

Tuesday's CMT Music Awards featured several surprise collaborations, including T-Pain with Taylor Swift and Keith Urban with Jason Aldean. But perhaps none was quite as jaw-dropping as when the B-52's took the stage with Sugarland, to perform their classic hit 'Love Shack'.

"We do it ['Love Shack'] live, so we had it worked out as far as the arrangement," Jennifer Nettles tells CMT, "but we wondered, 'How would it work to bring everybody in?'"

Jennifer's partner, Kristian Bush, had another idea: "We just wanted them to play it -- and we were just going to stand onstage," he joked.

Hey now, you're a country star?!

We were a little surprised to see Smash Mouth frontman Steve Harwell on the CMT red carpet Tuesday. But it looks like we'll be seeing a lot more of him in Music City. The singer of such catchy pop-rock songs as 'All Star' and 'Walkin' on the Sun' has gone country.

"I have been working on a country record for about a year now," Steve told The Boot before the awards show. "I'm co-writing with people here, jumping on the bandwagon. I just want this so bad. I want to break away. I want a solo career and want to prove to people that I belong and deserve to be here. But you've got to earn respect. So I'm moving here and already love it."

If you thought the Eminem-Elton John pairing at the Grammy Awards was odd ...

Taylor Swift has gone gangsta! The country darling is teaming up with rap superstar T-Pain for a top-secret collaboration that is rumored to be the opening number of Tuesday's CMT Awards. Taylor was even sporting some grillz at the rehearsal (see photo after the jump). She's up for four trophies, including the night's top award, Video of the Year, for 'Love Story.'

Brad Paisley is the latest country artist to get into the Twitter habit. And it turns out he picked up a few Twittering tips from an unlikely source.

MusicCityTV reports that Kevin Jonas of the Jonas Brothers has been spotted in and around Nashville, where he's presumably collaborating on songwriting projects. And while Brad has more than a few helpful songwriting tips he could share with the eldest JoBro, it's Kevin who's been schooling the singer-guitarist on the latest social networking craze.

Although Carrie Underwood herself might have something different to say about the idea, controversial R&B singer Chris Brown is reportedly considering recording one of his songs as a duet with a country artist.

Brown, who made headlines in February after the alleged beating of his girlfriend Rihanna, is currently in the studio recording new music. And one of the people he's working with, writer/producer Robert Allen, tells E! Online that a song he's working on, called 'Trapped in a Dream,' would be the perfect country duet.

Is TV's 'Ghost Whisperer' going country? The World Entertainment News Network reports that actress Jennifer Love Hewitt could be trying to scare up some new fans with a country tune she's recorded.

Love, as she's affectionately called by friends, released her first pop album in Japan at age 12. She followed that up with several releases in the U.S., none of which made much of a dent on the pop charts. Still, her boyfriend, comedic actor Jamie Kennedy, is quoted as saying, "I really want to make her a new demo for her music, because I think she should do singing again. She's so good."
