Biography:Valletta was born in Phoenix, Arizona. Shortly after her birth, her family moved to Tulsa, Oklahoma. She attended Booker T. Washington High School. She got her start in the fashion industry when her mother enrolled her in modeling school at the age of fifteen at the Linda Layman Agency. Initially, she did runway work at a local mall on Saturdays. However, her big break came after she cut short her hair and went to Europe.
A local agency sent the now 5'9" brunette to Milan where her first shoot was posing for Italian Vogue. Soon after that, Amber got her first big break; the cover shoot for French Elle magazine by Hans Feurer. Not too long after that, Amber, like most models began residing in Paris. Amber immediately became a modeling sensation, having picked up where fellow supermodels Cindy Crawford and Claudia Schiffer had left off. Photographers and magazines alike couldn't get Amber's face pasted on billboards and magazine covers fast enough.
Amber has since appeared in numerous prestigious advertising campaigns such as Versace, Calvin Klein's Escape, DKNY, Prada, Valentino, Jil Sander, Gucci and Chanel. She co-hosted MTV's House of Style with best friend and fellow model Shalom Harlow and she even became the face of Elizabeth Arden.
Although she didn't end up becoming the sociologist she wanted to be, Amber does use her position as a celebrity to support various charity events. In 1995, she organized a charity called Supermodels Stepping Out Against Hunger, a fashion show that took place in her hometown to benefit the Tulsa Community Food Bank.
Valletta has gone on to act in several films, been on the cover of magazines and in advertisements for Louis Vuitton, Calvin Klein and Versace and hosted MTV's House of Style with friend and fellow supermodel Shalom Harlow. Valletta was scheduled to appear on Punk'd on Season 6 Episode 3, along with David Boreanaz and Kristin Cavallari, but Kutcher had to move the prank played on Valletta to an episode later to make room for the prank played on Dallas Cowboys wide receiver Terrell Owens, which is based on his suspension on November 19, 2005, while playing for the Philadelphia Eagles.
