In last night's TOWIE (19 June), Ricky confessed to Jessica that he had two-timed her with another girl three or four weeks into their relationship.
Viewers have been left wondering what the future holds for the couple, but Ricky has vowed to prove to Jess just how much he loves her.
Ricky's admission has caused shock among fans and it appears he has now become embroiled in a Twitter spat with Nicola after she voiced her views on the matter.
During the episode, Nicola tweeted: "Ricky you no good tw*t!! Stop shouting, you cheated. @MissJessWright_ you are way too good." She added: "Ok so Mario is a tw*t and so is Ricky!!"
it appears Ricky later responded to Nicola's posts. He tweeted: "Hate people that get involved that know absolutely nothing about it.. get back in your glamour box and concentrate on your own boring life."
Nicola has since received a message of thanks from Jessica. She tweeted Nicola, saying: "Thanks for your tweets babe xx."
It also seems Ricky may be having a change of heart. Posting another message on the social networking site, he said: "I appreciate everyone's opinions good or bad... At the end of the day this is MY mistake and it's MY fault..I will fight for this I love her."
He also responded to a fan who accused him of not letting Jess speak on the show, adding: "Remember that a 10 min conversation is stripped down to a 10 second scene on television."
