Last month, Thomas Rhett appeared on Audacy's Rob + Holly where he chatted about the experience of working with Katy Perry on their track "Where We Started," sharing that the two "literally talked about our kids the entire time."

"We literally talked about our kids the entire time… how we're raisin' 'em and what we're feeding 'em," he shared. "I think that's what you do as a parent these days, you're just like, 'Oh, let me show you this one picture on my phone of my kid that you've never met!' "

Perry shares her 2-year-old Daisy Dove with fiancé Orlando Bloom.

Speaking to PEOPLE, Thomas Rhett echoed similar comments about how the musicians bonded over their families.

"I feel like when you're a parent and you talk to another parent it ends up being the majority of the conversation that you have because that's just what your life is consumed in," he said. "So to be able to talk dad-ing and mom-ing with someone like Katy was kind of hilarious, but awesome at the same time."
