2015 is shaping up to be a good year for Maddie & Tae. The two 19-year-olds have been going nonstop (like the Energizer Bunny), and are getting ready to hit the road on a major summer tour with Dierks Bentley.

Do they ever have time to sleep? Well, not really. But they do sneak in a nap every now and then, which is why Taste of Country caught up with the young singer-songwriters... in bed. That's right, it was a Maddie & Tae slumber party! And of course, girls will be girls. They talked about boys, shopping, clothes, and the pretty butterflies in their "Fly" music video.

"Mine was named Herbert," Tae Dye reveals. "Mine was Felicia," Maddie Marlow adds. "So I could be like, 'Bye Felicia!' whenever she flew away." Unfortunately, these butterflies weren't very well-behaved.

Dye explains, "There was a scene where I let go, and the butterfly is supposed to fly out. But Herbert would fly whenever he wasn't supposed to fly... and then he would fly underneath the machine, and almost died a couple times. Then when I was like, 'Okay. It's your turn to fly,' he just sat there."

"Felicia, she was tired. She was having a bad hair day, and she was just not feeling it." Marlow adds. "We had to put her back in her cage." Poor Felicia.

Maddie & Tae are eager for Bentley's Sounds of Summer tour to get started (Kip Moore and Canaan Smith will also be along for the ride.) And to say they are excited would be an understatement. Marlow gushes, "He texts us sometimes and I'm like, 'I'm trying to be cool here.' When my phone pops up with Dierks Bentley, I'm like 'Oh my gosh!! Okay, wait. He's supposed to be like my friend. I'm supposed to be cool.'"

The girls also demonstrated their band's pre-show ritual. "We get all the guys, like all these grown men to do this goofy little dance with us. And then we go out onstage," Maddie says. You'll have to watch the video to see it. Now if only they can get Dierks, Kip, and Canaan to do it this summer. Now we're talking!

The Sounds of Summer tour kicks off June 5 in Raleigh, N.C.
