Courtney Love is at it again. This time her target is Dave Grohl.

Love recently launched a Twitter tirade against the former Nirvana stickman alleging that Grohl tired to sleep with Kurt Cobain and Courtney’s only child, Frances Bean Cobain.

She’s alleged that Grohl hit on her daughter in the back of a car and that she thinks the Foo Fighters frontman is sexually obsessed with Kurt.

Frances has since responded, saying her “biological mother” should be banned from the social networking site.

Here's her statement: "While I'm generally silent on the affairs of my biological mother, her recent tirade has taken a gross turn. I have never been approached by Dave Grohl in more than a platonic way. I'm in a monogamous relationship and very happy. Twitter should ban my mother."

In response to the allegations, Grohl, through his spokesman, said: “Unfortunately Courtney is on another hateful twitter rant. These new accustions are upsetting, offensive and absolutely untrue.”
