When Luke Bryan isn’t taking the country music world by storm, he’s home with his wife, Caroline, and three boys. Late last year, Bryan took in his now 13-year-old nephew, Til, when his brother-in-law passed away — Bryan’s sister Kelly died in 2007. Now, Bryan is opening up about what his life is like with three kids living under one roof — he’s also helping raise his two nieces, Kris and Jordan — and how his two sons are adjusting to the change.

“Til lives with us. It's amazing to have a 13-year-old,” Bryan, 39, said during a concert appearance on “Good Morning America" earlier this month, as reported by Yahoo! News. The "Drink a Beer" singer even had a little on-air message for his nephew. “He got me in a headlock two nights ago and I’m admitting now, you had me. I couldn’t get out!” he said.

While Bryan shared that everything was going well at home, he did admit his wife has her hands full. “The boys are starting school today,” he said when speaking about why she wasn’t at the concert. “It's a lot of new challenges.”

Bryan recently told People that his two boys with Caroline, Bo, 7, and Tate, 5, are adjusting well to the new additions in their brood.

"It's been amazing watching them do so well with it. They treat Til like their brother, and Til does the same,” Bryan told the magazine. "Obviously my nieces and nephew, they didn't ask for this. Their life was amazing before Caroline and I took a more prominent role, even after losing their mother. Now my focus is trying to do what we can to help them."

In the wake of their family's tragic losses, the singer says he has kept himself strong through faith.

“I think with everything that's happened in my family, I just have to lean on my faith and the understanding that God has a plan for all of us. We just wake up every day and do our best.”

Bryan’s decision to speak out about his newly expanded family follows the recent release of his fifth studio album, “Kill the Lights.” The album debuted on Aug. 7. As of Friday, two of Bryan’s latest singles, “Strip it Down” and “Kick the Dust Up,” had two leading spots on iTunes’ country chart.

“I’m really excited about this album,” Bryan told “GMA” of his latest project. “I’m really just pumped up that the fans can finally get it.”
