Frankie wore a white off-the-shoulder dress for the cast party, which was being filmed in Stanford-le-Hope, Essex.
As newly-released pictures have shown, the party brought a bit of romance for Jessica Wright and Dan Edgar as the pair shared a kiss!
However, it also got pretty heated, as a fight appeared to break out between Fran Parman, James 'Diags' Bennewith, Georgia Kousoulou and Tommy Mallet in the middle of the dance floor.
Well, at least Frankie was well clear of the drama!
Joey Essex's sister Frankie made a surprise return to the ITVBe reality show last week, where viewers saw her comfort cousin Chloe Sims due to her current rift with her brother Charlie.
Frankie - who left the show in 2014 - hadn't told fans about her cameo, so her return was a welcome surprise!
