The whole cast flew over to the White Isle last month to film the opening two episodes of the new series, which premieres tomorrow night on new channel ITVBe.
We already knew that Arg and Lydia were getting close again in Ibiza and now we've got the picture proof as they were snapped embracing outside Es Paradis nightclub at the end of September.
Lydia told Reveal: "We went over to Ibiza and we were in the same hotel and we had a bit of a holiday romance. It was all really good but we're not actually official. We're getting on well and we have that chemistry. We were together for a long time as well so it's nice that we get to hang out."
Viewers saw feelings between the former couple brew up again last series, when Lydia returned to Essex following a brief time away. They'd split in December 2011 amid allegations of Arg cheating.
But will their holiday romance turn into something permanent?
Lydia would only tell us: "Who knows? I'm just going to wait and see what happens"
TOWIE returns with The Only Way is Ibiza on Wednesday 8 October at 9pm, exclusively on ITVBe.
