Back to modeling: Kent-born Brook has returned to modeling after pursuing an acting careerHaving been voted the Sexiest Woman in the World by the readers of FHM magazine, it's no surprise her 32E-26-36 hourglass figure has been chosen for the Spring campaign.
Ultimo creator Michelle Mone OBE said: 'Kelly is a natural beauty and is effortlessly sexy, making her the perfect choice for Ultimo. She epitomises the Ultimo woman and looks incredible in our new designs.
'This campaign is our most striking yet and represents the qualities of the new range; irresistibly sexy, luxurious, aspirational and feminine. The pictures really do speak for themselves.'
New face: Kelly has been voted Sexiest Woman in the World by the readers of FHM magazineKelly recently hit out at critics who have panned her attempts to break into acting, and she explained how difficult it had been for her to carve out a career for herself in the acting world.
She said: 'I never respond to critics. When I was at school no one said, "When I grow up I want to be a critic".
'It’s still a man’s world. I’ve had to fight to be something that isn’t just a pretty face or body.'
All brand new: Kelly models the new collection in a video promo with a soundtrack by AC/DCHowever, her latest role, in 3D movie Piranha, won't help the actress to be taken more seriously.
According to The Mirror, she said: 'It's just a big, fun B-movie - lots of boobs, blood, gore and drama. I don't think I'll be getting any Oscars for it.
'In Piranha, there's lots of cool people. It's about a lot of fish that eat a lot of buff boys and big-boobied girls. It's all set during spring break.'
