Josh Duhamel offers movie set visit for charity competition

Josh Duhamel is offering one lucky fan the opportunity to meet him on the set of his upcoming romance movie Safe Haven.

The Transformers star has asked his Twitter.com followers to hand over $10 to charity for the chance to win a trip to North Carolina, where he will shoot the big-screen adaptation of Nicholas Sparks' best-selling novel.

Donations will go directly to The Nicholas Sparks Foundation, a non-profit organisation founded by the author to support communities in need around the world.

In a post on his Twitter page, Duhamel writes, "Want to meet me and the cast on the Safe Haven set? Donate $10 or more for a chance to win a trip!"

The competition winner will also meet Duhamel's co-star Julianne Hough, who will play his lover in the drama.
