Rick Harrison, the star of the History Channel show "Pawn Stars," is getting sued by his 81-year-old mother. Joanne Harrison says her son has cut her out of companies, trusts and kept her locked out of a safe full of cash and silver. Harrison says the issues started when her husband Richard "Old Man" Harrison died in 2018. She claims after her husband's death, her son took over business elements and accounts that rightfully belonged to her. Joanne Harrison argues she's entitled to family businesses and holdings, including the Gold and Silver Pawn Shop in Las Vegas that rose to fame on the show.
