Gossip frontwoman Beth Ditto has hit out at Katy Perry saying she is “offensive to gay culture.”

28-year-old Ditto was speaking to British gay magazine 'Attitude' when she slammed Perry for her faux-lesbian hit single 'I Kissed A Girl'.

She described the track as a "boner dyke anthem for straight girls who like to turn guys on by making out or, like, faking gay."

Clearly consumed by loathing, Ditto ranted: "I hate Katy Perry! She's offensive to gay culture, I'm so offended."

"She's just riding on the backs of our culture without having to pay any of the dues and not being actually lesbian or anything at all."
