Courtney Love loves a good old rant and this time it's all directed and Foo Fighters front man Dave Grohl.

Courtney says, 'I Own Nirvana' following a bit of a melt down after her appearance at Brazilian Festival.

After storming off stage because a fan held up a picture of late husband, Kurt Cobain she only returned after her entourage got the crowd chanting 'The Foo Fighter Are Gay'....OK.

She then told the audience: 'I don't care what you listen to at home, but if a guy takes off money off my kid's table, fuck him.' The hole singer continued to slate the drummer in an interview after the gig backstage saying, that he 'didn't write one fucking note'.
