Katy Perry is back to being unattached. The 'Wide Awake' singer reportedly split with her PDA-loving boyfriend, Robert Ackroyd of Florence + the Machine.

Us Weekly reports that the extremely short-lived relationship came to an amicable end recently and that their hectic schedules are to blame. "It wasn't that serious," a source tells Us Weekly of Perry's relationship with Ackroyd. "It's not a nasty thing and they are still talking, but Katy told him to do his thing and they'll talk soon." Another source assured, "No hard feelings. She's really busy and so is he."

The couple first went public at Coachella -- very public, as they were all over one another!

”Backstage at the Artist Lounge at Coachella last weekend, Katy kept saying her boyfriend was the guitar player for Florence + the Machine," a source said last month. "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!”

It sounds like there's still an open door on this relaysh, so we'll see what happens when Perry takes that "f---ing vacation" she's been dying to have.
