Courtney Love fired off a Twitter missive in which she accuses former Nirvana member Dave Grohl of hitting on her daughter, Frances Bean Cobain.
Grohl angrily denied the allegation.
"Unfortunately Courtney is on another hateful Twitter rant," he said via his publicist. "These new accusations are upsetting, offensive and absolutely untrue."
What the Foo Fighters frontman is referring to is a series of tweets the 47-year-old Love, the late Kurt Cobain's widow, lobbed last night online.
