It’s the end of the line for Josh Groban and Kat Denning’s celebrity relationship. After spending two years as a celebrity couple, the two stars are calling it quits. According to EOnline.com, a source said, “It was a mutual breakup. They are still friends and care about each other, but it’s not the right time for them now as a couple.” Both Groban and Denning will be busy with projects this coming fall, but there is no doubt it will take some time to recover from the split.
