Jasmin threw the bash to mark the religious festival and all the cast turned up to Sugar Hut in Essex while wearing an array of gorgeous saris and kurtas.
There definitely seemed to be no expense spared and everyone was sparkling from head-to-toe in their jewel-encrusted outfits.
Ferne opted to wear a green sari while Billie chose orange and both girls completed their looks with dramatic make-up and beautiful head chains.
All the gang appeared to be at the party and Lydia Bright grabbed some of the cast for a fun backstage selfie. Posing together with Vas J.Morgan, Georgia Kousoulou, Leah Wright and Ferne, Lydia snapped the photo and shared it on Instagram.
Don't they all look incredible? Especially Vas!
Commenting on the photo, Lydia told her followers that she had picked the moment as number eight in her personal '100 days of happiness' challenge.
"Day 8. Celebrating Diwali with @vasjmorgan @fernemccann @georg_kxx @missleahewright #100DaysOfHappiness," she said.
Meanwhile, the other TOWIE lads also joined Vas in pulling out all the stops for Jasmin's party. Elliott Wright, James Lock and Tommy Mallet posed for a picture outside Sugar Hut in their regalia, with Elliott telling his fans: "Diwali party with the boys!"
Yesterday's scenes will air in the ITVBe reality show in the coming days and we can't wait to see what everyone got up to.
Glitz, glamour and a party - there was bound to be drama going on. It wouldn't be TOWIE otherwise!
