Courtney Love's apparently in one heck of a financial hole, and that has her fighting mad. Her lawyer tells E! News that the 'Doll Parts' purveyor is preparing to file a lawsuit "in the next 30 days" on behalf of herself and daughter Frances Bean Cobain against a slew of unspecified parties she claims "looted" millions of dollars from late husband Kurt Cobain's estate.

"Courtney's main interest is ensuring that her daughter gets the assets back that were stolen," says San Diego attorney Rhonda Holmes.

"Courtney is pursuing her rights on the criminal end against the people who stole, and her daughter and Kurt's estate are focusing on the financial aspect."

Plaintiffs will also include Cobain's mother, brother and two sisters, says Holmes.
