Tewes played the same character, Julie McCoy, in four different series: The Love Boat (1977), Charlie's Angels (1976), Martin (1992) and Love Boat: The Next Wave (1998). Her surname is pronounced like "tweeze". After her dismissal from The Love Boat in 1984, Tewes spiraled into drug addiction. She has now been sober for many years and makes her living doing voice-overs and radio commercials, as well as working as a cheese steward in Seattle. She says she used to spend 16 hours a day caring for her sick husband.
