After over a decade making country music, Little Big Town are officially Grammy winners. The quartet's song 'Pontoon' was named the Best Country Duo/Group Performance during the 2013 Grammy Awards pre-show webcast on Sunday night (Feb. 10). 

"We wanted one of these for so long!" Kimberly Schlapman said as she led her longtime bandmates onto the stage. Before the rest of the group got to speak, presenter David Alan Grier was brought to the microphone in a bizarre moment.

"I'd like to thank the Academy," Grier deadpanned before Karen Fairchild, Jimi Westbrook  and Phillip Sweet took over and thanked their management and label team. "This is such a long time coming for us, we're so thrilled," Sweet said.

While LBT have been nominated before, the win for 'Pontoon' is their first-ever Grammy. The group spent a busy week in Los Angeles leading up to their big moment. On Friday, they told Taste of Country that 'Pontoon' and the songs from 'Tornado' are their proudest moments.

"I'm proud of us that we did it because it was gutsy and some people thought we were crazy," Fairchild said. Now, they can relax and enjoy the show with smiles on their faces. They say they're looking forward to seeing country music shine -- and to seeing Justin Timberlake perform.

Also nominated in the Best Country Duo/Group Performance category were songs by Eli Young Band, Taylor Swift and the Civil Wars, the Time Jumpers and Don Williams with Alison Krauss.
