Chung celebrated her special day with a VIP dinner at The South Kensington Club in London, held by Elle Magazine and her fashion app Villoid.
For her birthday get-up, the model opted for a gorgeous baby pink floral dress with cut-out shoulder detail, teaming the girly design with sleek black kitten heels.
Chung kept her hair in a low-key chignon, but still looked super glam with a pop of dark berry lipstick.
The event hosts presented her with this pastel rainbow cake of dreams, which went down a treat with guests (including Alexa by the look of it!).
A number of celebs were also in attendance, including best pal Nick Grimshaw, models Jack Guinness and Laura Bailey, designers Alice Temperley and Charlotte Dellal and blogger Tanya Burr.
Total birthday goals.
