Cameron Diaz Dazzles at PFW Valentino Runway Show

Stepping out for her third day of fashionable festivities in the City of Lights, Cameron Diaz closed out her Wednesday (January 25) with a nighttime Paris Fashion Week runway show.

The "Knight & Day" darling dazzled in a white lacy cutout frock as she took to the Hotel Salomon de Rothschild for the Valentino Spring/Summer 2012 Haute-Couture catwalk display.

Earlier in the week, Miss Diaz took in the Armani Prive PFW showcase, at which she was asked whether anything caught her eye in terms of a possible Oscars red carpet dress.

To this, the 39-year-old replied, "You know, on paper, a dress with scales doesn’t sound so good. But Mr Armani made it work. It was chic but also amazingly avant garde. Nothing is obvious but it makes a major statement: that’s the beauty of couture."
