Kellie Pickler Getting Ready For USO Tour

Kellie Pickler is prepping for her USO tour. The singer says via Twitter that she has begun packing for the trip, and notes, quote, "Think I'm gonna leave the Red High Heels at home 4 this trip. Easier 2 jump in/out of helicopters in flats." The country star's upcoming trek will mark her third time heading overseas to entertain America's men and women in uniform. Pickler's last USO tour was in December 2008, when she, the Zac Brown Band, and Kid Rock spent five days visiting U.S. bases in Germany, Kosovo, and the UK as well as Iraq and Afghanistan. For security reasons the exact dates and locations for this upcoming USO tour haven't been revealed. But Pickler will be heading out to meet the troops with Jamey Johnson and Randy Houser.
