Now that filming for the ITV2 reality show has taken a break, the boys used their free time to flock to Chelmsford for the annual Duke of Essex polo event on Saturday (13 July).
Charlie was without his girlfriend Ferne McCann as he enjoyed a lads' day out with Mario, but it seems the hot temperatures proved too much for him.
Taking to Twitter, Charlie said: "Finally made it to Essex polo @Mario_Falcone .. 3 piece suit = boiling!"
Representing the best of Essex, Mario and Charlie - who both looked dapper in their tailored suits - were joined by the likes of former Big Brother star Aisleyne Horgan-Wallace and Dane Bowers for the sporting occasion.
During the event, Mario tweeted: "With @charlessims_ at the polo! Good day had by all x ."
In the last episode of TOWIE, the cast were merry as they partied with Big Mark Wright and Carol to celebrate their vows renewal, but there were also a lot of heartfelt chats, as Mario poured his heart out to ex-girlfriend Lucy Mecklenburgh, apologising for his infidelity and admitting that he still loves her.
