Jill Sobule (nope, me neither) released her 'I Kissed a Girl' in 1995, some 13 years before Katy Perrys No.1. Not only that but it has a completely different tune. Oh, and the lyrics aren't the same either. Apart from that Jill, your case is as concrete as they get.

SO to clarify - this whole story is based on some bitter woman who had a song with the same name as someone elses. Quite.

When will this madness end? Led Zepellin suing Will.I.Am for Heartbreaker? Bob Marley suing Blue for One Love? Jennifer Rush, Huey Lewis AND FGTH all ina legal war over 'Power Of Love? Get a fucking grip lady.

Jill claims Katy stole the title, saying it can't be coincidence as they were both signed by the same person. In an exclusive interview with The Rumpus she said:

"As a musician I have always refrained from criticizing another artist. 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, because that's not me."

No, you're not! Oh hang on...wait.

"Okay, maybe, if I really think about it, there were a few jealous and pissed off moments. Fuck you Katy Perry, you fucking stupid, maybe 'not good for the gays', title thieving, haven't heard much else, so not quite sure if you're talented, fucking little slut."

Good grief! Below is a clip of Jill's version. Safe to say it's the kind of song that hippies and ugly student girls like. To offer some balance to this story I've put a gallery up of Katy in a bikini. It's what she would want. True story.
