Sugarland are getting ready to wrap up their widely successful Incredible Machine tour next week, but the award-winning duo, comprised of Jennifer Nettles and Kristian Bush, aren't ready to put away their suitcases just yet. The two will head to Oslo, Norway, in December, where they'll take part in the all-star Nobel Peace Prize Concert.

The 'Stuck Like Glue' performers will join Jill Scott, David Gray, Matthew Morrison, Ellie Goulding and World Youth Choir for the Dec. 11 event. The concert will be held one day after the Nobel Peace Prize Award Ceremony, which will honor three recipients this year: Liberian President Ellen Johnson Sirleaf, Liberian activist Leymah Gbowee and Yemeni activist Tawakkul Karman.

Jennifer and Kristian aren't the only country artists who have been invited to perform for the prestigious event. Shania Twain, Lee Ann Womack, Willie Nelson, Dierks Bentley and Toby Keith have all previously joined the celebration.

Sugarland will play in Tallahassee, Fla., tonight (October 21) and Atlanta, Ga., tomorrow night (Oct. 22), before they play their final show in Indianapolis, Ind., next Friday, Oct. 28. The concert, which promises a few surprise guests, is a free show that will honor the seven lives tragically lost in the devastating stage collapse at the Indiana State Fair in August.
