EXCLUSIVEMichael Muhney, a big soap star who played Adam Newman on "The Young & the Restless" -- was fired last month after one of his co-stars complained to the brass that he grabbed her boobs -- on 2 occasions ... TMZ has learned.
Multiple sources connected to the show tell TMZ ... 38-year-old Muhney allegedly bullied and harassed 20-year-old Hunter King, who plays Summer on the show.
