The beautiful 23-year-old was reportedly paid a seven-figure sum to endorse the Milan-based label’s underwear and jeans lines for spring/summer 2010 in a sizzling billboard campaign.
Megan was shot in sultry black and white by photographers Mert Alas and Marcus Piggott in Los Angeles for the pictures, which are set to feature in major cities around the world.
Fashion legend Giorgio Armani said: “Megan’s young and sexy with a lot of spirit… she’s the perfect choice for the collections.”
And the actress isn’t the only gorgeous star showing off her enviable figure for the upcoming season's fashion lines.
Following her banned 2008 ad for Calvin Klein’s Secret Obsession fragrance, Eva Mendes has returned to the fashion house for a new set of racy pictures.
The Hitch star features topless alongside Keira Knightley’s ex Jamie Dornan in a series of photos to promote the label’s new Whitewashed jeans range.
Meanwhile, George Clooney’s girlfriend Elisabetta Canalis is the star of Roberto Cavalli’s spring 2010 underwear collection.
The 31-year-old Italian TV presenter travelled to London last November to shoot the campaign in a lavish 19th-century home.
Draped on an ornate couch in leopard-print bra and looking smoulderingly into the camera, she shows exactly why she’s won the heart of Hollywood’s most famous bachelor.
The pics were also shot by photographers Mert Alas and Marcus Piggott and their star is overjoyed with the results.
“The Cavalli brand has always been synonymous with the made-in-Italy excellence and known all over the world,” Elisabetta said.
“I am proud to represent it in this campaign, shot by two of the world’s greatest photographers.”
