Carole Baskin's Dancing with the Stars debut featured a commercial about the disappearance of her late husband.
The Justice for Don Lewis advert saw the millionaire's family and their attorney, John M. Phillips, reach out to the public for answers about his disappearance in 1997, urging anyone with information to message 646-450-6530 or 1-800-litigate.
In the ad, Gale, one of the animal sanctuary owner's daughters, said: "We are a real family and to us, he was daddy."
The family is currently offering $100,000 for information about his whereabouts.
Donna, another of his daughters, explained in the ad: "I'm Donna. I'm Don Lewis' oldest daughter. We need to know what happened to our father."
