What a mix-up!

Anne Hathaway surprised fashion fans when she chose a pale pink Prada gown over the Valentino creation she was set to walk the Oscars red carpet in, and apparently the last minute change was executed out of fear that co-star Amanda Seyfried's Alexander McQueen dress would look too similar to her own.

Valentino's camp sent out a press release Sunday just hours before red carpet arrivals began that stated the Les Miserables star would be wearing "a pink embroidered tulle illusion gown", so clearly the designer wasn't kept in the loop about her style switcheroo!

Presenter Jennifer Aniston was expected to wear a "nude embroidered silk tulle dress" also by Valentino, but many believe the A-list actress switched to her red strapless number after catching wind of Hathaway's similar style.

Basically, Anne changed her dress choice because of Amanda, and Jen changed her dress choice because of Anne!

At least all three lovely ladies avoided a matching fashion faux pas!
