In TOWIE's finale on Wednesday (30 July), viewers saw Arg pull out all the stops to win back Lydia with two very romantic gestures.
And still touched by his efforts, could Lydia be planning to get back together with her former beau?
Sharing a very sweet snap of the pair together at TOWIE's Grease-themed party, Lydia is pictured with her arms wrapped around Arg while he tenderly plants a kiss on her head.
Lydia's photo captures the moment Arg surprised her by re-creating the first time the pair ever said 'I love you' to each other. Complete with a Westlife tribute singer, choir, and his ballroom dancing skills, Arg went all out to surprise his ex-girlfriend.
Reflecting on Arg's efforts, Lydia cryptically captioned her photo suggesting she is ready to give their relationship another go.
She wrote: "Sometimes you have to forget the world and enjoy the moments."
Since the couple have grown close again this series, Lydia has held back her real feelings for her ex.
During a conversation at Leah Wright's wedding, a heartbroken Arg confronted Lydia about where they stand with their relationship.
Telling the 24-year-old to stop worrying about what other people thought, he said: "You're worrying too much...If I'm making you so happy why are you letting everyone else affect your life?"
While Lydia replied she "hates" everyone knowing about her private business as they all have something to say about it.
Could Lydia's message mean she is ready to forget about what other people might think?
Speaking after the show's finale, Lydia said Arg's gesture "literally melted her heart".
She said: "Arg has definitely proved that he loves me. Who knows what will happen with me and Arg... I don't think I'll rule it out now because I honestly can't believe how much he loves me, really. It's a bit of a shock to me. You never know, one day we might end up together."
And one person who clearly thinks the pair have a future, is Lydia's mum, Debbie Bright.
Since the couple split, Debbie has always had a soft spot for her daughter's ex and taking to Twitter yesterday, the TOWIE mum shared a picture of Lydia and Arg during the finale, along with the words "who said romance was dead."
It sure isn't for ol' romantic Arg who also surprised Lydia on the night with a pair of Carrie Bradshaw-esque heels that she has wanted for years.
