"Josh and Katy are very close friends and hang out, but they are not a couple," Groban's rep, Luke Burland, tells PEOPLE in response to rumors of a relationship between the two.
Perry, who split with Travis McCoy in January, is currently touring her One of the Boys record. Groban, who is working on a new album, attended her Los Angeles show in February.
