The reality star shared a photo of herself with her childhood sweetheart from when they were younger and it's safe to say the pair looked just as loved-up then as they do now!
While Lydia looks completely different in the snap, sporting a much more pronounced Essex glow and darker, curly locks, Arg and his dress sense are exactly the same!
Even now the Essex crooner still opts to slick his hair right back while teaming a shirt with a jumper tied around his shoulders.
Somethings never change, ey Arg?!
Captioning her photo, Lydia said: "When we was kids @realjamesargent #TBT."
Despite dating for four years when they were younger, Lydia and Arg's relationship came to an end in 2011 after Lydia found out Arg had been unfaithful to her.
But for TOWIE's biggest love story, round two could be on the cards as Lydia has finally admitted she is in love with her ex-boyfriend.
After returning to the The Only Way Is Essex earlier this year, Lydia has grown closer to Arg and he even pulled out all the stops to win over his former flame.
Putting on a big romantic gesture, Arg surprised Lydia with a pair of Carrie Bradshaw inspired shoes she had refused to take off him twice before. After telling Lydia he didn't want anyone else but her to have them, Arg then whisked Lydia off to a garden where a choir and a Westlife tribute singer was waiting for them.
As they arrived the singer burst into a rendition of 'Flying Without Wings' to help recreate a romantic moment the pair had once shared.
And it looks like all Arg's efforts a couple of months back seem to have done the trick!
While partying in Ibiza with the rest of the TOWIE cast, Arg and Lydia were spotted kissing and since returning, although claiming they are not yet official, the pair have both said they are willing to work at their relationship.
During the second instalment of Ibiza action on Sunday (12 October), Lydia was seen telling Arg that she thought there was "something special" between them and that she still loved him.
Following the episode, a more than happy Arg tweeted: "It's not official but going so well with @LydiaRoseBright. Boy have I grafted haha! Won't F things up!"
