Prior to Sunday night's Academy Awards Anne Hathaway switched dresses at the last minute because she feared she would clash with another actress wearing a similar gown.

Hathaway, who won "Best Supporting Actress" for "Les Miserables," intended to wear a Valentino gown with silver embroidery. However, she wound up donning her back-up choice - a pale pink Prada gown. Several critics skewered her pick, mainly because it emphasized her nipples. The dress even earned a Twitter handle: @AnnesNipple.

The actress told People.com: "It came to my attention late Saturday night that there would be a dress worn to the Oscars that is remarkably similar to the Valentino I had intended to wear, and so I decided it was best for all involved to change my plans.
 
"Though I love the dress I did wear, it was a difficult last minute decision as I had so looked forward to wearing Valentino in honour of the deep and meaningful relationship I have enjoyed with the house and with Valentino himself. I deeply regret any disappointment caused."

Apparently, the Valentino gown she hoped to wear clashed with the one worn by her "Les Miserables" co-star Amanda Seyfried. She was also criticized for her choice due to its ill fit and washed-out color.

Hathaway is a long-time fan of Valentino. The fashion house designed her wedding dress.
