What a guy! Luke Bryan is a super successful country singer and songwriter — but, most importantly, he’s a proud dad and uncle. In a revealing new interview with Good Morning America‘s Robin Roberts, the 41-year-old star and his wife, Caroline Boyer, candidly opened up about their family and revealed they “never thought twice” about taking in Luke’s sister’s three children when they needed a new home.

Seven years after Luke lost his brother, Chris Bryan, in a car accident, his sister, Kelly Bryan, tragically passed away from unknown causes in 2007. “Just when we started picking up the pieces with my brother, then my sister — we lose my sister,” Luke told Robin in his ABC News special, which aired on Monday, Nov. 6. “I’ve watched my family go through ebbs and flows where we get mad at God and we get mad at why this happened.” Then, in 2014, Kelly’s husband, Ben Cheshire, died, leaving their three children without parents. So, Luke and his wife, Caroline, took in their nephew, Tilden, 16, and college-aged nieces, Jordan and Kris, and are raising the trio alongside their two sons, Thomas, 9, and Tatum, 7.

“We never thought twice about [taking in Kelly’s kids],” Caroline told Robin during the interview. “You know, it was never something that [Luke] and I had to sit down and talk about. ‘Should we take this on?’ We just did that.” Funnily enough, Luke admitted he’s had to get used to raising a teenager since his two sons are still so young. “[Til and I] are buddies now, though, kinda. Until he makes me… that’s when I get onto him, I’m like, ‘All right, you’re making me be an adult; don’t make me be an adult!'” Luke joked.

This isn’t the first time Luke has opened up about his blended family. “You don’t want to sound like you love having them so much that you’re glad it’s the situation, but we’re honored to be doing what we feel was the right thing,” he told Billboard magazine in 2015.
