Katy Perry has ended her relationship with Gym Class Heroes frontman Travis McCoy, according to reports.
The couple are said to have split shortly before the New Year after spending the festive break together.
"It's a hardship, but she's regrouping," a source told CelebBuzz.
McCoy appeared to allude to the split in a blog post on December 31st.
After posting the lyrics to a break-up song by hip-hop group Main Source, McCoy wrote: "My Laptop is my new b–. LOYAL. LISTENS. and NEVER LET'S ME DOWN."
Meanwhile, Perry welcomed the New Year without McCoy at an event in Los Angeles.
