The Blue Crush actress debuted a fresh haircut while stepping out at a screening of the film Still Alice, held at the Sunshine Cinema in New York.
Kate looked as stunning as ever, flaunting a new bob 'do which fell just below her jawline, styled in a side parting with the lengths teased into a bouncy blow-dry.
She had her mane cut by celebrity hairdresser Harry Josh in preparation for her upcoming role in new film 90 Minutes in Heaven.
And it seems Harry was pretty pleased with his handiwork, taking to Instagram to showcase a snap while adding the caption: "Sorry folks couldn't wait for the reveal tonight, too many paps chasing her around! So here it is the stunning @katebosworth hair by me make-up by @hungvanngo."
We've always loved Kate's lengthy tumbling locks, but we actually think we prefer this chic shoulder-skimming 'do on her!
The actress joins a long line of celebs who have also cut their barnets into bobs recently, including Rachel McAdams, Vanessa White, Kendall Jenner, Elizabeth Olsen and Rosie Huntington-Whiteley.
