Taking to Instagram earlier today, the reality star chose to show off her new manicure on the social media site, but caused a frenzy when fans picked up on the diamond instead...
In her photo, Lydia can be seen with her gorgeous burgundy-hued "winter nails" on display, accessorising her new polish with very engagement-esque ring.
Fans, like us, were quick to try and work out whether the ring was on her wedding finger or not, with one asking the 25-year-old: "Are you getting married?"
However, it turns out it's just a false alarm and sneaky Lyds hadn't been so sneaky after all.
Not blinded by the huge rock, some of Lydia's followers were quick to point out it was actually on the wrong hand.
One user said: "Wrong hand maybe..." While another appeared to confirm: "The ring is on her right hand f****** hell."
If Lydia had been set to wed, fans would have been left slightly confused as she and co-star boyfriend James 'Arg' Argent are going through a rocky patch of late.
Fans of TOWIE will recall that Lydia was left upset by her beau, after Arg lied that he had stayed over at his friend Diags' flat. Arg had initially text Lydia to say he was with Diags, but was planning to stay at her mum's, not letting her know when his plans changed.
Frustrated that he would lie to her unnecessarily, Lydia has said she needs some time away from Arg.
The pair have been dating on/off for seven years, with trust issues plaguing their relationship. Concerned that her issues with Arg are "history repeating itself", she said: "You would have thought that James would have learnt by now."
Arg, meanwhile, has apologised to Lydia, but has admitted he is concerned about the future of their romance.
"Short term it's quite tough," he said. "But hopefully long term I will hopefully be able to sort things out... I know I haven't handled things the right way but I just like to think how close we've been, and how happy and in love we are, it would just be a great shame."
In scenes to be aired during tonight's episode of TOWIE, viewers will see Lydia break down in tears as she confides in BFF Georgia Kousoulou and Tommy Mallet.
Oh, we hope she and Arg can work it out!
