Don’t consider this a spoiler, consider it an early Christmas present – part of Carrie Underwood’s TV holiday special features her singing with Christina Applegate and Kristin Chenoweth, RadarOnline.com has learned exclusively.

The three attractive blondes sing a 1960s medley a spywitness told RadarOnline.com. And, the same source says you will be pleasantly surprised at how well Kristin sings!

The song was taped this week at CBS studios. The special is tentatively titled Carrie Underwood: An All-Star Holiday Special and set to air on Fox December 7.

Applegate was in a festive mood, taking photos with young fans. And the biggest surprise to our spywitness was Bo Bice arriving with a huge entourage! Bo has an entourage? Apparently he does!

David Cook was also at the taping, although he seemed kinda moody. Maybe he’ll cheer up by the holidays!
