Courtney Love's 19-year-old daughter Frances Bean Cobain is horrified by her mom's latest Twitter tirade.
She also slammed her mom's claims that Foo Fighters frontman Dave Grohl — who as her dad Kurt Cobain's former Nirvana bandmate has known her since she was a baby — had tried to seduce her. Grohl has already denied those claims, too.
"While I'm generally silent on the affairs of my biological mother, her recent tirade has taken a gross turn," Frances Bean said, according to People.

"I have never been approached by Dave Grohl in more than a platonic way. I'm in a monogamous relationship and very happy," added Frances, who has been engaged to musician Isaiah Silva since October.
"Twitter should ban my mother," she said.
Grohl responded to the tweets — sent from Love's private account @cbabymichelle to @davegrohl, which account actually belongs to a German student who shares the rocker's name — Thursday, too.
"Unfortunately Courtney is on another hateful Twitter rant. These new accusations are upsetting, offensive and absolutely untrue," Grohl responded.
Frances Bean's relationship with her mom has been icy for a while. When she was 17, Frances had her guardianship transferred to her grandmother and aunt and got a restraining order against Love, whom she accused of killing her pets.
Love's contact with Grohl hasn't been rosy, either. She has slammed him repeatedly in the past — most recently for letting the makers of the recent "Muppets" movie use Nirvana's "Smells Like Teen Spirit."
