Jess looked like a proud bridesmaid as she posed next to younger sister Natayla during Leah's wedding to Chris Tayler in Alicante.
'Dance All Night' singer Jess oozed sophistication in a plunging grecian style mint green dress, while clutching onto an elegant white rose.
The floor-length gown perfectly showed off Jess' svelte figure and finished off her look by accessorising with a matching headband.
With both Jess and Natalya sporting updo hairstyles, they made perfect bridesmaids!
It was a family affair on Thursday (17 July), with Jess' brother Mark and his fiancée Michelle Keegan in attendance, as well as Leah's brother Elliott Wright and his girlfriend Chloe Sims.
Close family friend James 'Arg' Argent and his ex-Lydia Bright also joined in for the celebrations.
