The girls were in full swing at the ITV summer reception bash held in a private house in Notting Hill and were seen posing with all of our TV favourites including Declan Donnelly, Jeremy Kyle, Leigh Francis and the cast of Broadchurch!
The girls managed to bump into anyone and everyone from the TV screens and naturally shared the photos on Twitter.
Jess caught up with the "fabulous" dance choreographer Louie Spence and had a good girlie chat with her "fave" person Zoe Hardman, who is co-star of Take Me Out: The Gossip alongisde Jess' brother Mark Wright.
Sam went in search of the popular Broadchurch cast and was seen snuggling up to the one and only Olivia Colman. Sam captioned the photo: "Me and my fav drama of all time #Broadchurch."
Sam also grabbed a quick photo with Australian singer Jason Donovan.
Apart from doing plenty of mingling, the girls looked fabulous in their black outfits.
Jess, who was without boyfriend Ricky Rayment, looked stunning as she showed off her curves in a long length strapless maxi dress. Jess teamed her sophisticated gown with a statement diamante necklace.
Meanwhile Sam, who this week flaunted her toned bikini body, looked equally glamorous in a jumpsuit.
The 22-year-old was planning on letting her hair down after tweeting before the event: "Excited for drinks tonight with my girls @lucy_meck @MissJessWright_."
Sam, who kept her hair in a high ponytail, shared her look with her Twitter followers beforehand and also showed off her new eyebrows.
She said: "Out on the town tonight! Massive thank u to @HeidiWorman for my tattoo brows! I love them."
After all the celeb-spotting, Sam and Jess made sure to hang out with co-star Lucy Mecklenburgh, who turned heads in a neon maxi dress. Sam simply captioned the photo: "The Pringles."
Other TOWIE stars in attendance included Chloe Sims, Jasmin Walia and Bobby Norris.
