In emotional scenes aired on Easter Sunday (5 April), the pair agree to give their tempestuous relationship another go... In sunnier climes.
Earlier this month, Elliott revealed he planned to move to the Spanish holiday resort so that he could open a new restaurant. And Chloe couldn't hide her tears when he told her.
But, in the TOWIE season finale, she told Elliott what he REALLY wanted to hear - that she would leave Essex to go with him!
During a highly-charged conversation, Elliott asked a newly-blonde Chloe to go with him abroad.
He said: "I don't want to lose you - but I know I can't expect you to just leave everything behind.
"But would you trade in pie and mash for tapas?"
Despite initial confusion when Chloe didn't quite understand what Elliott was asking - or maybe she just wanted him to spell it out - Elliott then had to ask in plainer terms.
He elaborated: "Will you come to Marbella with me, Chloe Sims?"
And the TOWIE audience were on tenterhooks as she answered: "Ever since you told me you were leaving, I've been seeing you in a different light. I used to see you as controlling - but all along, you were just being caring.
"Like the other day when I was getting my hair dyed blonde, you sat there with me the whole time. I thought you were being controlling but you weren't - you were being my mate."
Breaking down in tears, Chloe added: "How can I stay if you're not going to be here with me?"
After a romantic kiss, the pair confirmed they were back ON! Wooohoooo!
After the show, Chloe took to Twitter to say: "So many tweets after tonight's finale. I've had a lot of ups and downs this series... Thank you for all your support #towie #itvbe."
Elliott added: "Well that was #Emotional #MarbsHereIGo."
