"Bean, sorry I believed the gossip," she wrote. "Mommy loves you."
Love had taken to her private Twitter account earlier this week to accuse the former Nirvana drummer of hitting on 19-year-old Cobain and going home with her. Love said that she heard of the flirtation from her daughter's roommate and a driver, and went on to attribute Grohl's motivations to a sexual obsession with Cobain's father, Kurt Cobain.
Gawker published the tweets, prompting Grohl to respond with a statement, saying "Unfortunately Courtney is on another hateful Twitter rant. These new accusations are upsetting, offensive and absolutely untrue."
Cobain later responded by dismissing Love's claims and suggesting that Twitter ban her mother from the service.
Love sent out the apology through her public Twitter account.
