Chantelle, 29, was snapped leaving the bash and judging by the smile on her face, she'd had a great time.
Teaming her tailored shorts with a floaty white blouse and a pair of nude courts, Chantelle was clutching a gift of blonde hair extensions which she'd picked up inside.
Given that the party was held by Easilocks extensions, and that Chantelle is a fan of super-long tresses, it's no wonder she was looking so happy!
Chantelle was not the only celeb to attend the party, as she was joined by pregnant Katie Price, who covered her bump with a loose-fitting scarf and TOWIE star Lucy Mecklenburgh, who showed us how to nail summer elegance.
Since spitting from Alex Reid last year, Chantelle has found happiness with banker Nick Hogg and professed her love for him after just one month.
But last night was a girls' night and Chantelle attended the party with pals. We're sure Nick wasn't too upset about missing out on a hair extensions event!
