The Court of Appeal in London rejected her claim that she was denied a fair hearing because of pre-trial publicity about the case.
Andrews, 29, who was convicted at Birmingham Crown Court in July 1997, denied murdering Lee Harvey by stabbing him more than 30 times. She said a mystery motorist killed him after an argument in a country lane in Worcestershire.
She was brought to court but remained in the cells, waiving her right to appear before the judges.
Mr Harvey's parents, Ray and Maureen, welcomed the judgment. Mr Harvey said: "We now want to draw a line under Tracie Andrews, who took away so much of our lives and has never shown any remorse."Reuse content
