The party planner confirmed his decision to leave the ITV2 series after two years on Twitter today (September 9).
He said: "I had an amazing time on TOWIE and will miss it deeply.
"The time has come to move on to other things. It has been an amazing near 2 years."
And I will cherish the memories. I want to thank you ALL for the support and I will see you soon I'm sure. X— Charlie King (@CharlieKing85) September 9, 2013
King joined the show in early 2012 in series four. During his time on the show he has dated Gemma Collins and Danni Park-Dempsey.
Fellow star Chis 'Little Chris' Drake tweeted his support for King, saying: "Truly one of the nicest people I have ever met @CharlieKing85 #mates4life."
Former star Debbie Douglas wrote: "@CharlieKing85 you have been a true inspiration to all you have met and a role model to those who have watched you. #kindheart #kindsoul.
"Wishing you all the happiness in the world on your next venture my dear friend."
The Only Way Is Essex will head to Las Vegas for two special episodes next month, before the 10th series.
