Jillian Michaels is a quitter ... after announcing she's leaving "The Biggest Loser" ... she's high-tailing it out of the Hollywood Hills.
Real estate sources tell TMZ ... Michaels just sold her 3-bedroom modern for $2.15M ... her asking price. Her real estate agent was none other than Reza Farahan from "Shahs of Sunset."
Pretty cool pad ... gourmet kitchen and an outdoor pool. A little surprising ... no home gym.
We're told Michaels is headed for the 'Bu -- where gyms are unnecessary because everyone's already skinny and beautiful.
