American musician and actor Josh Groban is currently dating actress Kat Dennings, star of the sitcom "2 Broke Girls." The couple made their relationship public in October 2014.
Beth Behrs, Kat Dennings' co-star on "2 Broke Girls" and a long-time friend of Josh Groban's, acted as matchmaker for this couple, facilitating the pair's first face-to-face meeting. Before they officially met, Dennings and Groban had interacted with each other on Twitter, which quickly escalated to flirting, and each of them had expressed romantic interest in the other to Behrs.
Prior to his current relationship with Dennings, Josh Groban dated actress January Jones from 2003 to 2006.
