Kellie Pickler will soon head off on her third USO tour with pals Jamey Johnson and Randy Houser. Just don't ask her where she's going. Due to security concerns, that's top secret information. Kellie says, quote, "We never find out where we're going to be going until we get on the plane, and they hand us our tour book."

Kellie's last USO tour with Kid Rock and the Zac Brown Band took her to five different countries in five days for a total of nine shows. She says, quote, "We worked real hard, but it was completely worth it. We had a blast." In a recent Twitter post, Kellie added that she's not going to pack her red high heels for this trip because it's easier to jump in and out of helicopters in flats.
