They're on? They're off? We never can tell with these former flames, but judging by this latest picture Lydia and Arg are more than happy to be holidaying on the Spanish island together.
Cosying up for a poolside snap, a gorgeous make-up free Lydia and her ex-boyfriend Arg were all smiles as they posed for a cute selfie.
Alongside her photo Lydia wrote: "Ibiza madness @RealJamesArgent", before tweeting "Ibiza is killing it."
Well, someone is clearly enjoying her stay!
Since arriving in Ibiza, Lydia has been enjoying glam nights out with her TOWIE pals and has been spotted partying it up with Arg in tow.
The pair, despite not speaking after they first split, are now good friends and after Arg's attempts to win back Lydia in the last series of the show, they've got us all wondering will they ever officially get back together?!
Last series, we all thought it was possible after the pair seemed inseparable, but any hope we had was gone when Lydia told Arg she just wanted to be friends.
Heartbroken Arg then pulled out all the stops to woo his ex with a huge romantic gesture involving a pair of shoes and a rendition of Westlife's 'Flying Without Wings'.
Since the finale aired, Lydia has said she "wouldn't rule out a reunion" with Arg now she realises how much the Essex boy really does love her.
Could Ibiza be the place for romance to blossom?!
We guess we'll have to wait and see....
