Courtney Love launched a scathing attack on Dave Grohl at a Hole show in Brazil, saying he steals money from her daughter.
She also fuelled the recent rumour that Grohl left Nirvana in 1993 - or rather, says he was kicked out rather than quit as previously reported.
The tantrum was sparked by an audience member holding up a picture of her late husband Kurt Cobain, which led to her walking off the stage as shown in the footage below (via Antiquiet).
Hole's guitarist came back out and told the audience to chant "Foo Fighters are gay" to help ease Love back on stage, which she did once the audience began to cheer her back on.
Love then made a not-so-subtle dig at Dave Grohl, telling the audience: "I don't care what you listen to at home, but if a guy takes off money off my kid's table, f--k him."
The comments suggests that Love believes Grohl is not entitled to his share of Nirvana royalties. "If you don't write a song, you don't get publishing, you don't steal money from the child, the mom, the sister," she later ranted.
Dave Grohl was not the only subject of gossip for the Hole singer. She also insisted that former lover Billy Corgan of Smashing Pumpkins wrote endless songs about their relationship, and claims almost every song on "Siamese Dream" and "Mellon Collie And The Infinite Sadness" is about her.
Apparently, a line from one of their greatest songs "Disarm" ("The killer in me is the killer in you") is from a letter she wrote to Corgan.

Does Love have any right to make these claims, or is she having trouble seeing clearly after years of rock n' roll excess? Share your reaction to the outlandish statements in the comments.
