Dave Barnes has opened shows for some of music's biggest names, including Dierks Bentley, John Mayer, Bonnie Raitt and Taylor Swift. But it was his gig as the opening act for Lady Antebellum that is earning him some star power on his upcoming Christmas CD.

The celebrated singer-songwriter, who has written tunes for Billy Currington, Marc Broussard, Bebo Norman and many others, is getting ready to release a new set of holiday songs next month, with one of them featuring Lady Antebellum singer Hillary Scott. Their duet, 'Christmas Tonight,' is one of six original songs penned by Dave on the disc, which also includes remakes of popular classics like Bing Crosby's 'I'll Be Home For Christmas,' and 'The Christmas Song.'

Hillary, who is a fan of Dave both on and off stage, was happy to lend her voice to the project. "Dave Barnes is one of the sweetest and most talented guys I know," she gushed from stage earlier this year (quote via Country Music Is Love).

No stranger to sharing her talents, Hillary also sang on Luke Bryan's top-five hit, 'Do I,' which was written by Luke and her fellow bandmates, Charles Kelley and Dave Haywood. You can also hear her voice on a new songs by Maroon 5, 'Out of Goodbyes.' Hillary hopes the opportunities to collaborate with artists keep on coming. "Having each other to work with is so much fun, so it's only natural for us to gravitate toward people who love what we love," Hillary tells The Boot, "and becoming friends with them is icing on the cake."

Lady Antebellum are currently enjoying their first run as headliners on their own Need You Now tour. Their own Target-exclusive holiday CD, 'A Merry Little Christmas,' hits stores next week. Find the trio's full tour schedule here.
