Sharon Stone Picks ANOTHER Fight ... with the Nanny

Sharon Stone HATES her former nanny's guts -- like seething, fiery hatred -- and now she's suing her former help ... claiming the nanny ran off with $9,500 of Sharon's cash.

Stone has a bitter history with the woman -- Erlinda Elemen. Just last year, the nanny sued Stone claiming the actress was a tyrant of a boss who would often hurl racially charged insults her way.

Stone denied the allegations ... calling the case "frivolous."

But now, Stone is lashing back with a brand new lawsuit of her own -- alleging she loaned the nanny $12,500 back in 2010 ... but the woman only paid back $3,000.

In her suit, filed in L.A. County Superior Court, Stone claims Elemen stopped making loan payments in January 2011 ... one month before Elemen claims she was fired.
