And we don't blame her for looking so happy - she looked stunning!
The TOWIE star, 23, looked beautiful in an electric blue jumpsuit which showed off her slim figure and flashed just the right amount of cleavage. Not too much!
She teamed the outfit, from Nicole Scherzinger's Missguided range, with sky-high gold heels and blow-dried hair with plenty of bounce. S-E-X-Y!
Best pal and fellow TOWIE-star Ferne McCann arrived at London's Café De Paris alongside Sam, who was hosting a party in the famous celeb hotspot.
Ferne also looked spectacular in a white dress with feather trim, which showed off her enviably toned and tanned legs.
Before heading out, Sam tweeted: "Rocking two @NicoleScherzy @missguidedcouk looks tonight.. Filming then @RealCafedeParis later with the girls."
She also thanked Mars And Venus for a lovely blow dry ahead of her "big night ahead [...] with my girls".
We hope the girls had a well-deserved good night out after their recent troubles. Sam was recently diagnosed with Crohn's Disease, while Ferne split up with her boyfriend Charlie Sims after he cheated on her.
