American Idol-turned-country-star Carrie Underwood is returning the network that made her a star to host a variety special, The Hollywood Reporter has learned.

The two-hour special , tentatively titled Carrie Underwood: An All-Star Holiday Special, will air December 7 on FOX.

Carrie — the most commercially-successful artist to emerge from Idol — will perform a string of hits, holiday classics, songs from her upcoming third album Play On — available Nov. 3 — and participate in comedy skits.

Dolly Parton, Brad Paisley, and American Idol 7 champ David Cook will guest star.
