Move over, Kylie Jenner! Rosamund Pike is also trying to bring back the undercut. The Gone Girl actress debuted a shaved section at the nape of her neck at Monday’s What We Did on Our Holiday premiere in London. The partial buzz cut could be clearly seen thanks to a bobby pin-heavy updo. Meanwhile, below the neck down, the 35-year-old opted for a simple yet chic lace Erdem LBD with matching black pumps. The loose sheath covered her growing baby bump. The expecting star—who announced her second pregnancy in June—has been sporting a short bob haircut for the most of the year but this is a cool update for fall. We’ll be seeing a lot more of the British star in the next few weeks as her highly anticipated flick with Ben Affleck is set to hit theaters October 3.
