"Hot N Cold" singer Katy Perry's relationship with Travis McCoy of Gym Class Heroes is officially on ice. A source close to the couple has confirmed to E! News that the two called it quits just before New Years.
Perry, 24, who received her first Grammy nod for her smash hit "I Kissed a Girl," had been dating McCoy, 27, for about a year. The former couple hit the road together last summer for the Van's Warped tour and had recently returned from a vacation to Mexico for the holidays.
