Katy Perry's romance with Florence and the Machine guitarist Robert Ackroyd was short and sweet. The pair have reportedly already parted ways.

"It wasn't that serious," a source told Us Weekly. "It's not a nasty thing and they are still talking, but Katy told him to do his thing and they'll talk soon."

The couple made their debut roughly a month ago, when they were photographed at Coachella together.

"No hard feelings," said another source. "She's really busy and so is he."
