Cameron Diaz has been an Academy Awards red carpet fixture since she first attended the show back in 1998 with then-boyfriend Matt Dillon.
The 39-year-old star, who's known for her daring style, has worn several stunning gowns over the years.
In 2010, she looked her most glamorous ever in a strapless tulle Oscar de la Renta gown with gold embroidery, Cartier jewels and polished side-swept curls.
For the 2008 Oscars, Diaz -- who reportedly got ready in just 20 minutes -- wore a strapless pale pink Christian Dior by John Galliano bustier gown, Bulgari jewels, minimal makeup and a party-ready ponytail.
And in 2007 a brunette Diaz paired a white asymmetrical Valentino Couture design with dazzling Cartier emerald drop earrings and silver peep-toe shoes.
