The former Strictly Come Dancing star, 24, attended the premiere for new film Hummingbird in London and certainly turned heads in the pale pink sparkly number.
Chelsee's frock, which was designed by the TOWIE star, had one sleeve and a dramatic thigh-high split, meaning the actress was able to flaunt some serious flesh.
She wore her hair in big natural curls, rocked a pair of statement earrings and completed her look with smokey eye make-up.
We think Chelsee looked gorge and, the great news is, you can get the look too!
The dress, called Kristina, is available from Lipstick Boutique and is priced at £80.
Perfect for a special occasion. What are you waiting for?!
