Meanwhile, Aaron previously revealed he considers being at home to be like a vacation and gushed about he and his wife's mutual appreciation of music, which helped bring them together.

He shared: "Any chance I have to be at my house, I take it. I'm never at home, I'm always travelling. I never work in Los Angeles. Being at home really is a vacation for me and my wife.

"Music is our obsession. I fell in love with my wife at a music festival. We have concerts inside our living room. Whenever we're in town, we track down artists playing in Los Angeles and just reach out to their tour manager and see if they'd like to play our living room."
