Humes competed as Miss Thousand Islands in the 1973 Miss New York State contest, and she won the Miss Florida USA pageant and was third runner up in the 1975 Miss USA pageant behind eventual winner and fellow actress Summer Bartholomew of California.
She became the hostess of the game show Sale of the Century in late 1984 after a brief period of trying out for hostess/letter turner on Wheel of Fortune in 1982 (although she substituted briefly in 1979 for then-hostess Susan Stafford), which she ultimately lost to Vanna White.
