Lindsay Lohan's Hired Help -- I Can't Quit You

6/30/2010 2:15 PM PDT
Lindsay Lohan's former assistant -- the one who quit earlier this month -- is back doing LiLo's dirty work ... we're guessin' because the Naomi Campbell gig didn't pan out.

TMZ has learned Eleonore -- who was loving life yesterday as she schlepped around town, picking up bags of grub at the Newsroom Cafe in L.A. -- has been re-hired for a one month "trial run" ... because we're told quitters aren't to be trusted in Camp Lohan.

Our sources say Eleonore has been helping Lindsay out for the last six days -- or in Lindsay's world ... FOREVER.
