The fashion designer has been taking time away from Arg in recent days but both were in attendance at last night's Elbrook Charity Gala Dinner in London on Thursday with co-stars including Chloe Sims, Chloe Lewis and James 'Lockie' Lock, as well as Katie Price.
We wonder if they spoke? The last time they bumped into each other it all became every emotional when Lydia burst into tears and accused Arg of always making promises and not living up to them...
Interestingly, rather than posing on the red carpet with Arg, Lydia joined Chloe L and Lockie for pictures, while Arg posed alone.
Lydia looked pretty as a picture in her pale pink skirt and embellished silver and green top. Very princess-esque, right? Arg, meanwhile, dressed for the drizzly weather in a black overcoat.
Fans of TOWIE know that Lydia's been struggling lately over boyfriend Arg, who admitted to a relapse in his recovery. It prompted her to ask him for space as she sorts her head out.
Arg has been trying everything to win her back on side but on Wednesday night's episode Lydia sent him a text saying she still needed more time and she hoped he could respect that.
She said recently: "I do feel like I am an iron lady and quite cold with it all but I think that's because what James tells me, what he will do moving forward, I have heard that so many times before. He constantly promises me things he will do but when I give him another chance he never follows through.
"I am enjoying being by myself right now and having time out. That might change because my emotions are still raw and I'm still very angry but he needs to just give me a lot of space because it's just too much pressure right now."
TOWIE airs Wednesdays and Sundays at 10pm on ITVBe.
