Mistress Vieda is a dominatrix that becomes Chris' new girlfriend after meeting her on Craigslist in "Encyclopedia Griffin". As she escorts Chris to his room, she say "hi" to Peter, much to Lois' surprise and annoyance that she knows his name. Peter refuses to answer about how they know each other, trying to take a knee as in football to run out the episode.
Mistress Vieda is voiced by Allison Janney.
