One of our favorites, Carrie Underwood, has signed up to entertain troops on her first United Service Organizations tour of the Persian Gulf.

The 2005 American Idol winner - who was recently named CMA Female Vocalist of the Year and nominated for two Grammy Awards - will perform for and meet with service members on the tour.

Exact dates and locations of her shows in the gulf region were not made public by the USO.

"They never release exactly where the tours are happening, or exactly when they're happening. All I can share is that it is sometime before too long from now. But I don't even know the exact locations that she's going in the Persian Gulf," publicist Jessie Schmidt said.

Schmidt said USO officials approached Underwood about touring the Persian Gulf region several months ago and plans have been in place "for quite some time."

"She is completely excited about it," Schmidt said. "She does have some band members that are able to go with her over there, so they're just all really jazzed.

"When she does return from the tour we can say that she's just come back, and hopefully we'll have some photos that they'll service to the press from over there as well," Schmidt said.

Underwood also was seen Monday on a segment of the Oprah Winfrey Show taped last week, performing her hit song, "Jesus Take the Wheel," and joining fellow guests Tony Bennett, Josh Groban and Michael Buble for a rendition of Stevie Wonder's "For Once in My Life."
