Megan Fox sizzles as she strips off to advertise Emporio Armani underwear

Models are normally keen to try and find credibility by making the move onto the big screen.

But Megan Fox has gone the other way, forging a new career as a model after success in Hollywood.

Making the most of her reputation as one of Hollywood's most lusted after stars, she strips off for Emporio Armarni's 2011 Underwear and Jeans campaign.

The 24-year-old appears in a preview clip for the soon-to-be-released advert wearing next to nothing and showing off the body that landed her on Maxim's hot 100 list four years in a row.
