Josh Groban and Kat Dennings have ended their relationship after almost two years of dating.
"It was a mutual breakup," a source shared with E! News.
"They are still friends and care about each other, but it's not the right time for them now as a couple."
The Hollywood pair made their relationship official back in October 2014 when they stepped out together at the Carousel of Hope Ball in Beverly Hills.
"They were so cute together!" a source said of the stars.
As to what brought them together, the Broadway star admitted to Ellen DeGeneres that both bonded over their nerdiness.
"She's, well, she's such a brilliant and funny person," he gushed during an appearance on the talk show. "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.'"
