Hillary Scott of Lady Antebellum is keeping her iPod close at hand these days just to listen to a new song by John Legend. The song isn't a new single from Legend; it's a song the trio co-wrote with the R&B star.

"We had the opportunity to write with John Legend in December," Hillary explains to The Boot, adding that she's a huge Legend fan. "One of the first concerts I went to that wasn't country was Gladys Knight so R&B music has been a part of my musical background my whole life. We wrote a song with John that we're really proud of, but we don't know what the future holds for it yet, if we'll cut it or he'll cut it or somebody else [will]. Just to be able to turn on my iPod and listen to a song we wrote with him, and hear him sing the demo is awesome. I'm so happy we were able to do that."

Hillary, Charles Kelley and Dave Haywood got together as songwriters first before they formed Lady Antebellum. Charles notes that one of the interesting things about their success right now is that they have more opportunities to write with some of their heroes, yet the time they have to write is dwindling.

"It's that double edged sword," he reveals. "When we all moved here we wanted to be songwriters.So now to write with John Legend and Miranda Lambert and Luke Bryan is what we hoped we could do. And right now we're talking about writing with Ronnie Dunn soon. The other day I was trying to get that lined up, so I'm sitting there texting him ... 'Do you have a date' and he's like, 'I don't have a date.' So I'm thinking to myself, 'I'm texting Ronnie Dunn about writing.' This is a crazy world we live in right now. It's really exciting and a way for us to vent that other artistic side of us."

Lady Antebellum play the Travis County Expo & Rodeo in Austin, Texas on St. Patrick's Day, March 17, then pick up their tour with Tim McGraw on March 25 in Vancouver, B.C.
