Knox Bentley was born on October 9, 2013, in Nashville. My wife and I liked the name [Knox]. It’s simple—my name’s one syllable. It just popped up, and we stuck with it,” Dierks shared with PEOPLE at the time. Unlike his sisters, Knox prefers the rink to the stage. A passionate athlete, he plays on a travel hockey team and even co-hosted the 2023 NHL Awards alongside his dad. “Hockey plays a big part of my daily life,” Dierks said in a press release. “I’ve been to rinks all over the country with my travel hockey son. I coach his spring league games and spend hours in the local hockey store, telling him, ‘No, you do not need a new stick!’”
