The beloved grandmother passed away this week at the age of 80 following a short illness.
While Nanny Pat didn't appear in the episode, filmed earlier this month, she was remembered at the very end of the episode by way of an "In Loving Memory" card, featuring an image of Nanny Pat at her 80th birthday.
Nanny Pat didn't film any scenes for Essexmas but her name was mentioned throughout the episode as characters referred to her big 80th birthday last series.
A statement released by the family yesterday said: "Sadly our amazing, courageous and beautiful Nanny Pat passed away this morning after a short illness. We are overwhelmed by sadness, and the whole family ask for privacy at this horrible time."
Her grandchildren Mark and Jessica Wright have both said they are "heartbroken."
A rep for the show added: "We are absolutely devastated to hear the sad news about our beloved Nanny Pat. Patricia has been at the heart of TOWIE from the very beginning and we will miss her terribly. Our thoughts are with the Wright family at this very sad time."
Several TOWIE stars of past and present have paid tribute via Twitter, alongside celebrities including Jacqueline Jossa, Rylan Clark and Katie Price.
