Israeli supermodel Bar Refaeli has appeared completely naked in a black and white TV video commercial to promote her new underwear line Under.Me.

The promotional video features the model in a bath and doing outdoor chores such as mowing the lawn and cleaning the pool - in a pair of briefs and a shirt.

She appears nude in the bathroom while she looks at herself in the mirror. Her underwear range is called Under.Me, and is designed by the model herself.

On the product website, Bar explains her underwear collection: "I feel I look my best when I'm comfortable. Especially when it comes to underwear.

"My underwear is the clothing article closest to my body, and as such, I want it to complement it and not steal the show. There is nothing better than simple, comfortable, quality clothing.

"My work means I'm travelling all the time, rushing from city to city and wearing the most incredible, elaborate designs. I love it, but on my downtime I just want to relax and be myself. I don't want my clothes to define me. And that's the idea behind under.me - a focused collection of beautifully-made basics that look good and feel amazing. That's all I need.

"Because underneath my clothes lies the real me. Nothing else."
