Luke Bryan has some advice for female country singers. The country star tells Entertainment Weekly thathe doesn't know why it's harder for women to make it big in country music, but he has noticed something about the ones that do. "They can wake up early at 5 a.m., throw a hat on, roll into a radio station, hang with the guys," he says. "They kind of have to be able to hang with the guys but also be feminine and pretty, and it's just a tough dynamic..." Bryan also concedes it's a difficult genre for young women to break into. "It's tough for a girl to, at the age of 16, start hitting the honky-tonks," he says.
