Olivia Wilde got a little wild with her hair color.

The 32-year-old actress debuted a new blonde 'do on Tuesday night, and looked nearly unrecognizable. "Oh what's up, BLONDE LIFE," Wilde captioned a selfie of her fierce new hairstyle.

The mother of two made her look even edgier by sporting a low-cut suit jacket, sans blouse, for an event with her pal Kate Mara, who stepped out in a similar fashion. "When you roll up to the party with your new look and it turns out you just single white femaled your friend you haven't seen in a year," Wilde captioned a photo of herself laughing with Mara. "So fun checking out the new #TiffanyHardWear collection tonight. Thanks for having us @tiffanyandco! #TiffanyPartner #iloveyoukatemara."

A source tells ET that the new hairstyle is for Wilde's upcoming movie role in A Vigilante, which begins filming on Monday.

This is the second new 'do Wilde has debuted since giving birth to her and Jason Sudeikis' daughter, Daisy, in October. Wilde chopped off her long locks in December, announcing that she was getting rid of her "Melania [Trump] hair."
