Over the weekend, Lewis joined co-stars Chloe Lewis and Georgia Kousoulou on the party island of Ibiza.
Sharing a photo via Instagram, he said: "Ocean beach with my gally but someones missing @lydiabright @missgeorgiakx @chloelewis91."
Lydia was one of the first ones out in Ibiza, but her holiday has come home and she is now heading back to Essex.
In TOWIE's series finale, Lewis and James 'Arg' Argent's friendship got back on track after Arg made a public apology and let him play bass with his wedding band.
The pair fell out over Arg's treatment of Lewis when he was appointed manager of Arg's band. Lewis had also felt let down because he had been nothing but a good friend to Arg during his stint in rehab.
Despite a hostile meeting earlier on, it all changed at the carnival party when Arg apologised to Lewis in front of guests.
Before inviting Lewis up on stage, Arg said: "We have been friends a long time. A good 10 years. When I was going through my bad times, he was there for me. He's always been a real, true, loyal friend. I do feel I've let Lewis down and I want to apologise for what I've done. I'm sorry."
