Katy Perry has split from Rob Ackroyd.
The 'One That Got Away' hitmaker has decided not to pursue a relationship with the Florence + the Machine guitarist - who she met at last month's Coachella Music Festival - because she felt their respective working commitments would make seeing one another regularly too hard.
A source close to Katy - who separated from husband Russell Brand in December after 14 months of marriage - said: "The main thing which led to her split with Russell was spending the majority of her marriage to him on tour and she said dating Rob felt like being with Russell all over again.
"It's a shame as they both liked each other but Katy wants to be able to have a relationship with someone she isn't constantly having to work out what time zone they're in.
"Rob was gutted but Katy said she didn't want to get in too deep and then break his heart so it was best to cut things off before they got serious."
The split has come as a shock to friends as Katy had appeared smitten with the musician and they were in "constant" contact.
The source added to the Sunday Mirror newspaper: "Rob was the first guy Katy had been with since splitting from Russell.
"She was still extremely fragile but had told pals their two weekends at Coachella together made her feel 'sexy and alive' again.
"Even when Rob left to continue touring America with Florence they would speak on the phone up to three times a day and she'd be constantly texting him."
