Just one day after she was introduced as the new face of designer Philipp Plein’s clothing collection, Lindsay Lohan showed off her sexy style.

The Mean Girls actress worked it for the camera today during a waterfront photo shoot in Bellagio, Italy.

Vision in white: Lindsay stepped daintily down the aged stairs leading from the Villa to the waterfront

Wearing a flowing grey and white, animal print cocktail dress, Lindsay waited patiently as Plein gave her directions and a beauty team helped the star get camera ready.

Once she was finished with hair and make-up, Lindsay was the picture of high fashion.

In addition to the cocktail dress, she wore a pair or orange shorts with a matching cropped jacket and a white blouse underneath.

The designer, who is clearly pleased to have the star on his team has said: ‘Lindsay is a beautiful, highly acclaimed actress and model. We will be able to create unique images: Refined and luxurious, but also full of sensuality.’

On Saturday Lindsay sat in the front row of Plein’s Spring/Summer 2012 fashion show.

Argh! The actress refuses to walk the plank
