The first time Caylee Hammack met Miranda Lambert, she'd already solidified plans to join the country superstar's Fall 2019 Roadside Bars & Pink Guitars Tour. Still, she was so nervous to finally meet Lambert in person that she wasn't sure if she'd even be able to say "Hello."

"I sat there for a moment panicking, wondering, 'Do I talk to her or do I not?'" Hammack says. "Finally, I introduced myself. She was so very sweet. It was like a little girl's dream."

Long before she became Lambert's tourmate and fellow country artist, Hammack was a fan. "I remember growing up, listening to "Kerosene" when I first started singing. All I wanted was to be like her," the rising artist explains.

"She was strong. She was independent. She was a woman breaking through the market," Hammack says of Lambert. "Being able to go on tour with someone I looked up to, it's unreal."

Music aside, Hammack and Lambert have one major thing in common: their mutual love of animals. Lambert's animal-focused charity, MuttNation, is celebrating its 10th anniversary in 2019.

"And I realized -- I wanted a farm, but [I realized] I want to have all the little animals that have disabilities and can't find a home," Hammack goes on to say. "One of my friends said, 'That's more like a petting zoo.' Well, I want a petting zoo. Just for me."

In both music and life, Hammack shares a kinship with Lambert that she hopes to further white the two are on tour. "I hope that we're spirit sisters," she adds.

The newest iteration of Roadside Bars & Pink Guitars tour will kick off on Sept. 13.
