Katy Perry is single once again.
Katy's latest boyfriend, Florence + the Machine rocker Robert Ackroyd, was no Russell Brand because he couldn't lock the "I Kissed A Girl" singer down.
According to US Magazine, Katy has already kicked her cute rebound to the curb. A source told the gossip mag:
"It wasn't that serious. It's not a nasty thing and they are still talking, but Katy told him to do his thing and they'll talk soon. She's really busy and so is he."
Katy and Robert made their affection public when they were photographed boo'd up at Coachella, but now it's over.
Robert might have been a rebound, but at least he can say he made "Fireworks" with Maxim's fourth hottest chick in the world!
