Katy Perry 'a f***ing thieving slut'

Jill Sobule has accused Katy Perry of stealing her song title for her breakthrough hit 'I Kissed A Girl'.

The singer-songwriter recorded a track of the same name in 1995, albeit with completely different lyrics, music and instrumentation, but noted that "you can't copyright a title... bummer".

Sobule told The Rumpus: "I was, 'well, good for her'. It did bug me a little bit, however, when she said she came up with the idea for the title in a dream.

"In truth, she wrote it with a team of professional writers and was signed by the very same guy that signed me in 1995. I have not mentioned that in interviews as I don't want to sound bitter or petty... 'cause that's not me."

She added: "Okay, maybe, if I really think about it, there were a few jealous and p***ed off moments.

"So here goes, for the first time in an interview: F**k you Katy Perry, you f**king stupid, maybe 'not good for the gays', title thieving, haven't heard much else, so not quite sure if you're talented, f**king little slut."
