I'm a celebrity: Gemma plans to outclass last year's top jungle babe Myleene Klass as she is set to join the cast of reality TV show I'm A Celebrity...Get Me Out of Here

Gemma said: "I am delighted to be the Face and Body of Ultimo D-G. The collections are fantastic - at last big cup lingerie which has sexy and practical collections - I love it!"

Michelle Mone, creator of Ultimo, who famously fell out with Penny Lancaster and Rod Stewart after dropping the rocker's wife for his ex-Rachel Hunter said: "Gemma was fantastic to work with and she looked stunning in the first ever Ultimo D-G cup lingerie."

Gemma, who used to date Manchester United ace Cristiano Ronaldo, but is back with on-off boyfriend, Wigan Athletic footballer, Marcus Bent, added: "It's certainly going to spice things up for me.

"And when a girl feels sexy it's usually her boyfriend who gets the treat too."

The ex-Hollyoaks star - who's gone from blonde to brunette overnight - will not be replacing Girls Aloud member Sarah Harding who models the A-C cup range for Ultimo.
