London: Supermodel Helena Christensen may have crossed the landmark age of 40, but she has come back from semi-retirement with a bang posing naked except for a pair of running shoes in an advertisement for Reebok.
The stunning full-length photograph shows her leaning against a ladder as if about to use it to climb the burnished steel wall in front of her.
But most observers would be forgiven for not noticing such background details or even the trainers she is wearing.
The Danish-born model is 41 and the mother of a 10-year-old son. But age has certainly not withered her and she is still in envious shape.
Launching the campaign, Christensen said the shoes technology was perfect for her busy schedule.
"Living in New York, I like to walk everywhere, so to have trainers that tone your legs and butt as you walk is fantastic," she said.
Nudity is run-of-the-mill for Christensen, who said that she is comfortable with being naked in public.
"I have no problems with showing my body. I`m Danish. Everyone`s naked on the beaches. We don`t really care," she had said in a recent interview.
Christensen rocketed into the stratosphere as a catwalk model and magazine covergirl after appearing naked in the music video for Chris Isaak`s 1991 hit `Wicked Game`.
In the past few months she has also posed naked for Elle magazine and with Eva Herzigova and Claudia Schiffer, for ID magazine.
