From June to September 1968, along with Frank Sinatra, Jr., she co-hosted Martin's summer substitute musical comedy hour, Dean Martin Presents the Golddiggers. She also made multiple appearances on the many other variety shows proliferating 1960s television, such as The Andy Williams Show, The Hollywood Palace, The Ed Sullivan Show and This is Tom Jones. She first appeared on television on her father's show "The Merry Mailman", a popular children's show in New York.
