Cheska attended the prestigious MINT Polo In The Park in London on Saturday (8 June) and was pictured sipping cocktails with a whole gang of her cast mates.
Sisters Francesca and Olivia Newman-Young were at the event, along with Stevie Johnson, Josh Coombs, Phoebe-Lettice Thompson and Oscar Ligenza.
Together, the stars hung out in the VIP area while also watching the horses and their riders in action.
Cheska embraced the sunny weather with a gorgeous printed dress from Amelia's Attic, along with a bright yellow statement necklace.
Francesca, Olivia and Phoebe kept it smart in blacks, whites and greys, while the boys all wore coordinating white shirts and tailored jackets.
It seems the MIC pals had a great day, with most of them tweeting the group photograph to their fans.
Francesca also shared a picture of herself and Cheska, adding: "What a great day! #neonchic #tanenvy." Gorgeous!
