Katy Perry is back on the market again after splitting with her latest beau.
Katy had been seeing Florence And The Machine guitarist Robert Ackroyd after they went public at last month's Coachella Festival.
But the short-lived romance obviously wasn't to be and the couple have split.
"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," a source told Us Weekly.
"She's really busy and so is he."
It could pave the way for a reunion with her ex-husband Russell Brand...
The split comes off the back of rumours he was unhappy at seeing pictures of Katy with Rob at Coachella, which according to Grazia magazine, prompted him to re-evaluate his relationship with the singer.
He was said to have written a heartfelt email to Katy, and a source told the mag: "Word has it Russell was 'seething with jealousy' when he saw pictures of her with Rob. He apparently feels he gave up on their relationship too easily."
The comic also recently admitted he was still in love with his ex-wife.
"But that doesn’t mean I regret it or anything. I was very happy to be married with her. She’s such a beautiful human being and I just have only love and positivity for her."
Meanwhile, Katy also appeared on Ellen's US talk show and - in a very round about way - spoke about her split from the British comic actor.
“I think it’s important to start breaking down the idea that to achieve your dream you always have to be perfect or flawless or live in some kind of fantasy world," she said. "So that’s why I decided to put everything into [her forthcoming film]... in the most tasteful way.
