Beloved castmember Nanny Pat - real name Patricia Brooker - has passed away at the age of 80 following a short illness.
Today, Georgia said: "We are all truly saddened by the loss of our beautiful Essex queen nanny pat who is irreplaceable & forever in our hearts. We have decided to hold back on the launch of #bygeorgiak & will launch in the New Year...
"Thoughts are with the Wright family."
Georgia had been planning to launch By Georgia K - a fitness, fashion and beauty website - just before tonight's The Only Way Is Essexmas special, which airs at 10pm on ITVBe.
The show will pay tribute to Nanny Pat by including an 'In Memory Of...' card at the end of the episode. A statement released on behalf of TOWIE said: "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."
Nanny Pat's grandchildren Mark and Jessica Wright have both said they are "heartbroken" about their loss, while TOWIE stars including Lydia Bright, Gemma Collins, Chloe Lewis and James 'Arg' Argent have all paid tribute via Twitter.
