Katy Perry is reportedly dating Florence + the Machine guitarist Robert Ackroyd.

The 27-year-old "Firework" singer was apparently overheard referring to Robert as her "boyfriend" at California's Coachella festival earlier this month.

"Backstage at the Artist Lounge at Coachella last weekend, Katy kept saying her boyfriend was the guitar player for Florence + the Machine. She and a bunch of friends were supposed to go see Dr. Dre together, but Katy said she was waiting to watch her boyfriend perform," a source told Life & Style.

The pair were photographed holding hands whilst watching Rihanna perform with Calvin Harris, and Robert later appeared to refer to Katy by her initials on Twitter. "Best Coachella ever. Scratch that, best weekend ever. Dre, Snoop, Pac, Nate, Fiddy & KP," he wrote.
