The House sitter was the woman who greeted House when he tried to crash Cuddy's Thanksgiving Dinner in the Season 6 episode Ignorance is Bliss. She was portrayed by actress Gabrielle Thomas.

House finagled an invitation from Cuddy who gave him the address for her sister Julia. House was hoping to damage her relationship with Lucas Douglas, who had also been invited. He made the three hour drive to her house after checking the address to ensure that Cuddy wasn't trying to pull a fast one on him. However, when he arrived, he found that Julia and her family had gone to Hawaii. The sitter had prepared a turkey sandwich for him at Cuddy's request.
