Watch Ellen DeGeneres Scare Josh Groban (Video)
Josh Groban also talks about his "brilliant and funny" girlfriend Kat Dennings.
Josh Groban opened up on Ellen about his girlfriend Kat Dennings -- and explained that a few iconic comedies played a big role in why they first got together.
"She's well she's such a brilliant and funny person," he shared. "Humor is such a huge thing for me, so the fact that we could talk about Monty Python and all sorts of weird other things, I was like, 'OK, yeah, we're on the same page.'"
Elsewhere in the chat, Groban talked about performing the National Anthem at the Kentucky Derby ("very nerve-wracking"), and even managed to have a surprise freak-out moment, courtesy of Ellen DeGeneres.
