The Holidays, Country Style

In the middle of the song, a surprise guest vocalist joins Rascal Flatts onstage—Jamie Foxx! "I'm speechless," Oprah says. "I'm never speechless!"

"We had to get you," Jamie says.

Gary and Jamie say they concocted the surprise with Oprah show producers—despite the fact that Oprah isn't a fan of surprises. The group just couldn't resist giving Oprah an unexpected holiday treat. "Jamie and ourselves did this song on our new record, and we know how big of a fan you are of Jamie," Gary says. "So, Merry Christmas! Happy New Year! Happy Thanksgiving!"
