Los Angeles: Actor-singer Josh Groban and actress Kat Dennings have reportedly gone separate ways after two years of dating. However, their split is amicable and the two remain good friends, reports eonline.com. "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," a source said. Groban and Dennings began dating in 2014. They made their first appearance as a couple in October that year, when they were spotted at the Carousel of Hope Ball in Beverly Hills. That was when the "2 Broke Girls" star heard Groban for the very first time. Later, the pair praised each other when they had separate sit-downs with Ellen DeGeneres on her show, "The Ellen DeGeneres Show". In his own interview with the comedienne, Groban called his then-girlfriend "a brilliant and funny person".
