On tonight's 'ACM Girls Night Out' CBS special, Ronnie Dunn serenaded Sugarland singer Jennifer Nettles with one of her own songs, the 2007 platinum hit, 'Stay.'

"Jennifer, my love," Dunn said as he took the microphone. "You've been an incredible friend to me, and it's an honor to sing this song tonight. I hope I can do it justice."

Nettles was invited to the event to be honored as one of only two female artists in the academy's history to ever write and perform the winning Song of the Year for 'Stay,' an achievement that she alone can take credit for. She sat perched in her throne at the side of the stage and watched as her country music peer, formerly of Brooks and Dunn, poured out the same emotion that she put into the song originally.

Though, Dunn's unique male touch gave an entirely new element to the song, and the 'Bleed Red' soloist received applause from both the audience and Nettles as he drew the last note.

"Thank you so much, that was really, really beautiful," Nettles said to Dunn, still in awe. "It's wonderful to be included in such beautiful -- and talented -- company. That was great."

Tonight's event honored female artists the Judds, Miranda Lambert, Reba McEntire, Martina McBride, Loretta Lynn and Carrie Underwood -- as well as Nettles -- for their great achievements in the industry.
