Country music fans have come to expect a little eccentricity from legendary crooner Willie Nelson, but he pulled off a real shocker this time: He cut his hair. ...Nelson's waist-deep, reddish pigtails have long been one of the singer-songwriter's signature features.

She said, "there's a lot of maintenance."
