Courtney Love is having a tumultuous week. Following recent blog-feuds with Billy Corgan and Ryan Adams – not to mention a newly scribed rant about Madonna – the widow of Nirvana frontman Kurt Cobain is being sued for $975,000 by London & Co.

Love allegedly failed to pay the management firm its commissions for the partial sale of her share of Cobain's songbook. Courtney reaped $19.5 million in the 2007 deal but has yet to pony up the five percent fee London & Co. asserts it is owed. Ironically, Love threw stones at Ryan Adams in a MySpace post this past Saturday, claiming she was herself the victim of a financial misdeed.

It seems there were "29 American Express cards that [she] didn't know existed that were connected to a few hundred bank accounts" and only recently discovered that there was an $858,000 tab she alleges belongs to Adams. In a lengthy rant, Love wrote of how the Brooklyn-based singer-songwriter somehow financed his 2003 album 'Rock N Roll' and all related expenses from an account that is tied to her daughter Frances Bean Cobain's trust fund money.

In an unrelated but subsequent blog post, Courtney also announced that she has decided to forgive Madonna for blowing her off earlier this year. "I don't dislike Madonna, I just wish she had returned a call I made a few months back," wrote Love. "We're extremely different types of people and different types of artists. However a lot of our mutual friends tell me that we're a lot alike.

"We don't have any relationship presently, but our karma seems a bit intertwined," Love added. Note to the Material Girl: Run like hell!
