"It is still kind of weird sometimes if I'm in a restaurant and my song comes on," she says. "We're sitting there and we all kind of go, 'oh cool.'"
Over the past few years, Lila, who has sold more than a million records, has spent her weekends and school vacations performing across America. Despite all this, she tried to hold back her music career so she could finish high school. She just graduated.
"I think everybody chooses their own career path that they want to take," she says. "For me, that was been to stay in school and get an education, and then move on to bigger and better things."
At Steilacoom, she tried to be just a normal teen. "She's a normal girl," says her friend Brian. "You wouldn't know just by meeting her that she's a star."
Lila's first performance was with her dad's country band at a local Moose Lodge. She was four.
When she was 13, she signed her first record contract. At 17, she had released two hit records. She has already performed with some of the biggest names in country and pop music, including Barry Manilow.
A lot has changed in the past 18 months. Her mother, Gretchen, used to travel with her everywhere. Today, her mother stays at home.
"She's not going to do anything that she doesn't want to do anyway, no matter what anybody tries to tempt her with, and I'm pretty confident of that," Gretchen McCann says.
Now that she has graduated from Steilacoom, Lila is very excited about her future. "I'm ready to sell millions," she says. "It's time now."
