Stella is Peter Griffin's new deaf co-worker at the Pawtucket Brewery, replacing Opie.
When Peter first meets her in "The Blind Side", he is surprised to find out how astute she is, but she explains that she knows how to read lips. Intrigued, Peter asks if her if without hearing, her other senses have been enhanced, such as if she can smell if he farts from across the room. She explains that she can't smell that, but that due to her extra reliance on vision, she can often notice subtle tells about a person, such as if they have farted, due to slight changes in their body movements. Peter then tries to give an example by uncontrollably spasming while he farts, to the point that she could have been legally blind an still seen it. even able to tell when he farts by Peter's movements. When Quagmire meets her, he is inspired to hold a disabled ladies night at The Drunken Clam.
Stella will return in "Peter Problems".
Stella is voiced by Marlee Matlin.
