Carrie Underwood's upcoming album seems to suggest the country singer could be entering a new phase in her career, but pregnancy might just down the star's plans.

Pregnant Carrie Underwood Dishes On Halloween Weekend Plans 

On Friday Taste of Country offered a complete look at the full track list for Greatest Hits: Decade #1, which is due out in December. The new record includes mostly old hits from the country star, including Blown Away and Before He Cheats.

There are thirteen songs on the two-disk set, and while three tracks are never-before-released versions of existing songs, the album only includes two completely new features. The first is Underwood's latest single Something in the Water. The other, which has yet to be released, is Little Toy Guns.

Carrie Underwood's Top Pregnancy Moments So Far 

Taste of Country suggests Underwood's greatest hits project is designed to reflect on old work and function as a transition into the new, but the singer's recent pregnancy announcement could put another album on hold.

Back in September Underwood revealed that she and her husband Mike Fisher, who plays in the NHL for the Nashville Predators, will be expecting their first child together. Concerned about being a responsible parent, the singer could take time away from the studio to be with her child, which would put a delay on any new material.
