The best friends starred together on The Only Way Is Essex for many years before Lucy quit the show to focus on her fitness and wellbeing business. And we've missed her on our screens ever since!
Lucy and Lydia were snapped en route to celebrity hotspot SexyFish in Mayfair, London on Thursday evening (14 April) looking super glam. Obvs!
Fitness guru Lucy was chic 'n' smart in her fitted trousers and jacket, teamed with an olive cami, while Lydia braved the cold, wearing a black playsuit with unusual white lace sleeve detailing.
Aww. We love these two.
Lucy and Lydia both appeared in the very first series of TOWIE back in 2010, when Lucy was dating Mark Wright and Lydia was dating Arg. How things have changed for Lucy. Not so much Lydia!
It was Lydia who left first, departing at the end of series seven to clear her head and get away from Essex and then-ex-boyfriend Arg, but she returned for a brief appearance in series nine, before rejoining the cast in series 11 and rekindling her relationship with true love Arg.
Lucy, meanwhile, left in series ten to focus on her Results With Lucy business and hasn't returned at all, despite many of us wanting even just a tiny cameo appearance! And sadly, that will probably stay the case as she told us last year: "I miss the socialising part of it. I loved going out with the girls and catching up, but it does come with a lot of stress filming that show and that's the part I don't miss. I like being a viewer now."
The 17th series of TOWIE ended this week but it returns later this year.
