Carrie UnderwoodCarrie Underwood has a little advice for recent finalists from her musical alma mater 'American Idol' -- dance with the one that brought ya!

The superstar says she finds it strange that contestants will change their musical style upon leaving the show, especially since fans -- through their votes -- tell them exactly what they want to hear from them.

"I feel like any contestant that ... that does well on 'Idol' has to stay true to what people voted for," Carrie tells Reuters News Service. "I've seen it happen a few times where people are one thing on the show, and then they get off the show and try to do something else."

Idol champion Kris Allen and runner-up Adam Lambert are both releasing albums this month, while third-place finisher Danny Gokey is set to release a country CD early next year.

Carrie has stated she's a fan of both Kris and Danny. She'll be joined by 2008 'Idol' winner David Cook on her upcoming holiday special, set to air Dec. 7 on FOX.
