Sex and the City's Kristin Davis endorses Dead Sea skincare products and will star in The Dead Sea for a new ad campaign to promote a particular Dead Sea skincare line.

She has landed a free trip to Israel's Dead Sea so she can be well versed as the spokesperson for the Dead Sea beauty products.

She said swimming in the Dead Sea is "like being on the moon with water."

After having a pedicure at a spa that uses a Dead Sea cream, she felt that the product was miraculous, and said that "the minerals make it really rich and obviously our feet need some help after wearing high heels. It was amazing."

The 48-year-old singer, was excited when her Kabbalah mentor Karen Berg told her about a "rejuvenating" product which helps keep lines and wrinkles away.

A source told Britain's Daily Express newspaper: "The product uses natural salts and minerals from the Dead Sea and claims to have extraordinary rejuvenating powers. Madonna is hooked. She has started using these products on her face morning and night, and all over her body."

"She could clearly afford to buy far more top of the range creams but it's the Israeli ingredients that have her hooked."

ABC's Good Morning America ran a television special highlighting the benefits of natural skin care products made with minerals from The Dead Sea. The special said that, "People travel from all over the world to slather themselves in nutrient-rich mud from Israel's Dead Sea. Legend says it was the Queen of Sheba who first believed in the mystical healing powers of the Dead Sea. Then Cleopatra traveled from Egypt to build the world's first spa there. Today Hollywood royalty, such as Julianne Moore and Susan Sarandon, use products from the salty sea."
