Having dined out with co-star Georgia Kousoulou, the pair soon bumped into Lauren, who was an original cast member of the show.
Posting a photo to Instagram, Lydia wrote: "After filming dinner @wearezizzi and look who we bump into 'its only LG,' so nice catching up with the this one. Never fails to make me laugh. #TOWIE."
