Italian tailor Mario has been suspended from the ITVBe reality show and so was not allowed to join the cast in Marbs for their usual antics.
Taking to Twitter before the show, Charlie - who quit TOWIE in the middle of series 14 earlier this year - said: "Watching #Towim and not being in it... Has made it so much more entertaining haha."
He later added: "One thing this #Towie ep is missing... @Mario_Falcone #Body #Tatts was going to mention banter but..."

Replying to Charlie's tweet, Mario said: "Hahaha you know mate x."
Meanwhile, Ricky Rayment also told fans he was watching the show last night. Last month, Ricky announced his decision to leave TOWIE after three years, after mutually agreeing with producers that the time was right for him to move onto other projects.

Ricky tweeted: "Don't forget @OnlyWayIsEssex Marbella is on tonight! I may not be in it but I'm still supporting the show and everyone in it! Good luck guys."
TOWIM saw laughter, emotion and potential romance on the cards, as the boys were full of banter, Danielle Armstrong split with boyfriend James 'Lockie' Lock and new boy Peter Wicks was causing a stir among all the girls.
