The Celebrity Big Brother star arrived at the Odeon West End in Leicester Square for the private screening of new documentary film Super Juice Me! and looked positively spring-like in yellow trousers.
The glamour model, 29, dressed her killer curves in the cute banana-coloured skinnies, teamed with a dark sleeveless cardie and a white vest which just about contained her all-natural GG breasts.
Casey joined the likes of Sarah Harding and Alesha Dixon at the film launch, who both rocked black-and-white patterned outfits.
The new documentary follows self-titled 'juice master' and lifestyle coach Jason Vale as he puts eight people on his 'Juice Only' diet for 28 days.
Jason worked with Katie Price in 2005 when he helped her lose two stone in three months after the birth of her second child Junior.
Imogen Thomas also attended the premiere in London, and showed off her fab legs in a short white dress.
The former Miss Wales, 31, has recently dropped a dress size after deciding to shape up at the beginning of this year with a strict diet and exercise regime.
