Frances Bean Cobain: Dave Grohl Never Hit On Me!

According to a report by Gawker, Courtney Love took to her private Twitter account to accuse Foo Fighters frontman Dave Grohl, 43, of hitting on -- and possibly sleeping with -- her 19-year-old daughter with the late Kurt Cobain, Frances Bean Cobain.

"I hear from Frannie's roommate that @davegrohl hit on frances," Love, 47, wrote, in a series of nonsensical tweets. "I'm not mad at her, him i am about to shoot dead." Love added that she had received confirmation from "reliable sources and a driver" that her daughter and Grohl did in fact have a tryst at his Laurel Canyon home. In her final tweet, Love referred to him as a "gross old man macking on kurt cobains only child."

An outraged Cobain opened up to Us Weekly on Thursday about her mother's recent accusations against Grohl.

"While I'm generally silent on the affairs of my biological mother, her recent tirade has taken a gross turn," Cobain tells Us. "I have never been approached by Dave Grohl in more than a platonic way. I'm in a monogamous relationship [with the Rambles' Isaiah Silva], and very happy."Adds Cobain, "Twitter should ban my mother."

The singer's recent diatribe is just the latest in a string of attacks on Grohl. Previously, Love had accused the former Nirvana drummer of squandering the band's finances and profiting from his association with Cobain, who committed suicide in 1994.

Grohl also quickly shot down Love's accusations, issuing a statement Thursday through his rep.

"Unfortunately, Courtney is on another hateful Twitter rant," the rocker explained. "These new accusations are upsetting, offensive, and absolutely untrue."

Love and her only daughter have certainly had their own share of issues over the years. Cobain currently has a restraining order out against her estranged mother, and cites the troubled singer's incessant drug use and erratic behavior in her decision to distance herself from Love.
