Urban is getting ready to finish his own North American tour, which is due to wrap Dec. 16 following several gigs in Ontario. Those dates can be found at his website.

The three-time CMA Entertainer of the Year has been on the road since April supporting his latest No. 1 album, "Love, Pain & the Whole Crazy Thing." He also released a best-of collection, "Keith Urban Greatest Hits: 18 Kids," last month.

Next year's trek will give Underwood a chance to showcase material from her new album, "Carnival Ride," which debuted at No. 1 on The Billboard 200 after selling more than a half million copies its first week out. Lead single "So Small" is currently at the top of the Hot Country Songs chart and is also making waves at pop radio.

Last month, Underwood scored three American Music Awards, including Favorite Country Album for her multiplatinum-selling debut, "Some Hearts," which spawned five No. 1 singles.

The singer has one more gig on her schedule this year: the Dec. 11 Tuesday Night Opry at Nashville's Ryman Auditorium.
