The reality TV star wore a pretty Little Mistresses dress to her own birthday party (June 7), which she celebrated at Retro Feasts in Mayfair.
Arriving at the pop-up eaterie with her boyfriend Josh Gunn - who does not appear on the E4 show - Cheska glowed with happiness in a peach and gold Grecian-style dress.
Best friend Ollie Locke wasn't far behind, along with fellow co-stars Andy Jordan and Louise Thompson who proved they are still very much the couple.
Olivia Newman-Young wore a classic LBD for the occasion, contrasting with her sister Fran's more colourful light blue frock which she teamed with a cool black leather jacket.
During the evening, Cheska tweeted updates to her family, friends and fans.
Alongside a super-cute picture of MIC's latest couple Andy and Louise, Cheska wrote: "The best couple in Chelsea - LOVE you Louise and Andy!"
Cheska also shared a picture with Fran and Louise, with the message "loving my girls".
Binky Felstead was nowhere to be seen at the party, despite the former best friends recently making up on the reality show.
