The "You Raise Me Up" singer said he is happy in his relationship with the 28-year-old "2 Broke Girls" star, reported Hello magazine.
"We're having a wonderful time and enjoying every minute of it. I don't think it's about being in the same industry. Kat could be a doctor or a pet psychic, she could be anything and she's just one of the kindest, most understanding people I've ever met, so really it comes down to who she is as a person," Groban said.
