AceShowbiz - Courtney Love has apologised after accusing Nine Inch Nails star Trent Reznor of "systemic abuse" and attacking the remaining members of Nirvana over a royalties agreement.

The Hole frontwoman opened up about the "mega aggressions" she has encountered over the years and insisted she was tired of "being scapegoated" by "clowns" when the treatment she's experienced and witnessed has been ignored in an Instagram post she quickly deleted.

She ranted, "Here's a few receipts from some mega aggressions I've had to deal with, make myself small for, stop righteous lawsuits over, ('we are not doormats' my sponsor always quotes to me) due to male privilege in all its vile toxicity (sic). When @sharonstone was asked if she had any #metoo's, she just laughed. We only get 1 right?"

"I've had enough of this (s**t) from these clowns leaning into my being scapegoated for breathing, for my husband's death, for my 'overt' sexuality, because I'm an addict, etc, and a WOMAN, for over 27 years (sic)."

Courtney insisted she's "over being made small" and slammed former Nirvana drummer Dave Grohl's reputation as "the nicest guy in rock" before turning her attention to Reznor, who she branded a "creep" and claimed she witnessed the Nine Inch Nails frontman abusing "girls as young as 12" when she was on the road with Hole.

Hours later, Love released an apology, accepting she had been "insensitive" and was sorry to "those I've hurt."

"I need to apologize for my recent post," she wrote. "It was insensitive and it was wrong."

"No matter how I feel, there are real people behind my words and I need to learn to be more responsible with my words. I am truly sorry for those I've hurt. I will do better."
