Megan Fox turns up the hotness in an unique activity stopping underwear advert for Armani: She is widely considered to be one of the most beautiful women in the world. And Megan Fox has just done a little bit more to cement that reputation. The 24-year-old actress poses provocatively in a brand new advertisement for Giorgio Armani jeans and underwear.

Reclining on a battered leather couch, the star shows off her curvy figure in a black lacy two piece. In another sizzling photograph, the star shows off the tattoos on her bare back as she poses in just a pair of Armani jeans. The script on her shoulder, from Shakespeare's King Lear reads: 'We will all laugh at gilded butterflies.

And another tattoo on her ribs reads: 'Those who danced were thought to be quite insane by those who could not hear the music.'The shoot will form part of the spring 2011 campaign and will be appearing on billboards from next month. Tennis ace Rafal Nadal also features in the campaign for the designer's jeans wear range, with a picture which shows off his toned torso. He replaces Real Madrid star Cristiano Ronaldo, who was the face of Armani men's underwear.

Megan this week looked stunning in a pale pink shimmering Armani Privé gown as she attended the Golden Globes awards with husband Brian Austin Green. But her career in modelling seems to be a little more successful than her recent acting efforts. Her latest film Jonah Hex flopped at the box office, while 2009 indie flick Jennifer's Body didn't do much better.

Meanwhile,  Passion Play, a film starring Mickey Rourke and Bill Murray had its release date delayed after it premiered to negative reviews at the Toronto Film Festival last year. She has two new films lined up - Friends With Kids, alongside Jon Hamm and Kristen Wiig - and crime thriller The Crossing.
