LOS ANGELES (Reuters) - Lisa Marie Presley, the only daughter of Elvis Presley, says she is facing financial ruin and has filed a $100 million lawsuit accusing her former business manager of negligence and mismanaging her finances.

Her ex-manager has filed his own lawsuit, accusing Presley, 50, of squandering her famous father's inheritance because of her lavish lifestyle. The lawsuit seeks $800,000 in unpaid bills.
