ROSAMUND Pike, wow.

The Gone Girl star hit the Oscars red carpet in a red lace custom Givenchy Haute Couture gown, blowing onlookers away in the sexy, strapless frock with a daring front split.

E! Fashion Police host Kelly Osbourne said of the Best Actress nominee: “She has knocked it out of the park. It accentuates her tiny waist, the ruching, the split. She has seriously delivered tonight.”

Giuliana Rancic added: “This for me was the best dress she’s worn all awards season.”
