Jess and Ricky looked glam as they headed to an Essex nightclub on Saturday (15 February) to film Mario's celebrations with their co-stars.
Jess showed off hew short-cropped hairdo and stunned in a black dress, while Ricky was suited and booted in a black suit.
The couple enjoyed a romantic Valentine's Day on Friday (14 February), with Ricky treating Jess to a meal and presenting her with a trip to Paris in April.
Also in attendance at Mario's party was James 'Arg' Argent, Ferne McCann, Bobby Norris and James Lock with his girlfriend Danielle Armstrong.
Ferne, who looked amazing in a midnight blue floor-length gown, showed off her best pout as she jumped in a snap with Jess and Danielle.
Captioning the photo, boutique owner Jess said: "Last night so funny."
The group, who kicked off filming last week for the new 11th series last week, appeared to be in good spirits as they posed for photos throughout the night.
