KATY PERRY has been accused of stealing a song title for one of her biggest hits.
Singer-songwriter Jill Sobule has said the star stole the title of I Kissed A Girl, a track with the same name that she recorded in 1995.
Sobule's song has completely different lyrics, music and instrumentation and noted bitterly that "you can't copyright a title... bummer".
She said: "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."
