Series 13 of the Essex-based reality show wrapped up two weeks ago. Charlie, who is dating co-star Ferne McCann, had been absent for most of it after deciding to take a break to focus on his latest business venture, Charlie's Deli.

The Christmas special of the ITVBe reality show will hit screens on Wednesday 10 December. Filming is already underway with the likes of Ferne McCann and Danielle Armstrong getting festive in France.
