Cosette made Fantine very, very upset. Us Weekly has brand-new details on what went down between Les Miserables costars Anne Hathaway and Amanda Seyfried the day before the Academy Awards -- and caused a panicked Hathaway to ditch her planned Valentino gown in favor of a Prada creation for her Oscar-winning night.

An insider close to the situation tells Us Hathaway learned during an Oscar rehearsal at Hollywood's Dolby Theatre on Saturday, Feb. 22 that Seyfried planned to wear a dress notably similar to hers to the ceremony. After Hathaway asked about her pal's dress, Seyfried graciously shared an iPhone snap of the Alexander McQueen creation.
"Anne was like 'WTF?!'" the source reports. "She started throwing a fit!" The 30-year-old Best Supporting Actress victor, however, "never told Amanda she had to change the dress." Still, Seyfried, 27, was ruffled by Hathaway's tirade. "Amanda didn't want to deal with it and left" the rehearsal, the source notes.

But the drama didn't end there -- spilling into Oscars Sunday, as Hathaway fretted over the switch-up with her glam squad at home. "Anne made the fashion, make up, hair, and jewelry teams wait at her home for hours as she decided what to do about the dress debacle," a second insider tells Us. The star also "asked for silence so she could rehearse her singing for the Les Mis tribute at the Oscars. It was a painfully long experience."

Hathaway acknowledged the kerfuffle in a surprising statement released by her publicist earlier this week. "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," the "I Dreamed a Dream" singer said. "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 honor of the deep and meaningful relationship I have enjoyed with the house and with Valentino himself. I deeply regret any disappointment caused."
"I kind of can't understand why Anne didn't wear the Valentino gown, anyway," the first source opines. "She was the one winning the award, not Amanda. Who cares?"
