Lucy caught up with Jessica Wright, Ferne McCann, sisters Sam and Billie Faiers and several friends for dinner on Saturday night (8 March).
Jess, who looked chic in a white vest top and striped blue shorts, posted plenty of photos of their wild night out on Instagram.
The girls clearly missed each other as they showered one another with kisses while posing for photos.
Captioning one snap, 'Dance All Night' singer Jess simply said: "Reunited @samanthafaiers1 @lucymeck1."
In another photo posted to Instagram, Jess and Lucy are pictured sitting in the back of a cab. Commenting on the snap the day after, Jess said: "Think @lucymeck1 & I had a few too many last night."
Minnies Boutique owner Sam also put her recent illness behind her to enjoy a night out with her close friends.
Celebrity Big Brother star Sam has recently been diagnosed with Crohn's Disease following her bout of illness in the CBB house, but has had all the support of her friends since her diagnosis.
Captioning the group photo, Sam simply said: "Love my girls xxx."
Pregnant Billie had previously shown off her outfit ahead of the girly evening, choosing to dress her baby bump in a black knee-length dress.
Reality star Billie, who is expecting her first child with fiancé Greg Shepherd, teamed her LBD with towering neon heels, while sister Sam went retro in a knee-length leather skirt, Giuseppe shoes and a black T-Shirt with the words 'This Is A Love Song' emblazoned on the front.
Elsewhere, Lucy looked chic for the night out and added a splash of colour to her outfit wearing a canary yellow mini dress. She also cuddled up to Sam for a photo and said: "Love my @samanthafaiers1."
Lucy departed from TOWIE during the Christmas special in December after deciding to take a break from the show.
Since, she's been focusing on her clothing store, Lucy's Boutique, as well as managing her successful fitness businesses, Results With Lucy, where she has also begun hosting bootcamps across the UK.
It was also reported earlier today that Lucy is in talks to host her own TV show in an effort to help people lose weight.
