It seems Anne Hathaway wasn't the only celebrity to make a last-minute switch and not wear a planned outfit to the 85th Annual Academy Awards.

Hathaway admitted on Wednesday that she ditched a custom Valentino gown for the Prada dress she ended up wearing and now sources revealed that Django Unchained star Kerry Washington also eschewed a custom-made gown designed specifically for her by Marchesa.

Washington, 36, ended up on best-dressed lists for the strapless coral Miu Miu floor-sweeping gown she wore to the Oscars in Los Angeles on Sunday. The gown won rave reviews for the Swarovski crystal-embellished bust that was composed of coral paillettes and silver beading with a bow just underneath it. She accessorized the look with matching coral satin clutch by Prada, Chopard earrings and a Fred Leighton cocktail ring.

Her dress may not have gone over well with the head of the movie studio behind Django Unchained, according to a report. Harvey Weinstein of the Weinstein Company that produced Quentin Tarantino's film is married to Georgina Chapman, the head designer for the fashion label Marchesa. Chapman reportedly created a custom gown for the Scandal actress to wear but at the last minute Washington changed her mind. She went with the strapless coral Miu Miu instead of the planned Marchesa gown.

Sources said people in the fashion industry with inside knowledge of the situation were surprised by Washington's switch- they assumed that the actress would not want to upset Weinstein.

"Isn't it career kamikaze to upset Harvey's wife on such an important night?" a source told New York Post's Page Six. Another source confirmed the report to Us Weekly.

Hathaway rejected a custom dress designed by her friend Valentino Garavani because it was too similar to her Les Miserables co-star Amanda Seyfried's Alexander McQueen gown.

The Devil Wears Prada star made a "difficult last-minute decision" to wear a pale pink satin Prada gown instead of a dress designed by Valentino, according to a statement she released on Wednesday.

Hathaway issued a formal apology to Valentino because the Italian fashion house sent out a press release before the Oscars confirming that the actress would wear one of its dress. In Hathaway's formal apology, the actress wrote that she "deeply regret any disappointment" she may have caused. Hathaway did not mention Seyfried in her statement.
