Known for her iconic red carpet looks, Natalie Portman debuted her new hair transformation at the 68th Ballon D'Or Ballon Football Awards in Paris last night (28 October) - and we're officially obsessed with her latest haircut.

Taking to the popular celebrity bob trend that we've seen Julia Roberts, Halle Berry and many more sport recently, Natalie's glossy brunette bob is making us want to go shorter this autumn/winter.

Ditching her long bronde locks for a shorter, more dramatic hairstyle, the Hollywood actress opted for tousled, voluminous waves for the special occasion.

While the star has previously had a bob haircut, this time Natalie has differently gone for more of a dark chocolate brown hair colour.

Styled and cut by her well-known celebrity hair stylist, Phillippe Mensah, shared a video of Natalie's new hairstyle on his personal Instagram story last night too.

The actress was also seen wearing a glamorous navy gown to compliment her new brunette locks.

Featuring a flattering low-cut neckline and flowy short sleeves, Natalie teamed her navy look with stand-out silver dangly earrings and matching statement silver rings.

With her new haircut definitely turning heads on the red carpet, we think her dark, brunette haircut is the photo you'll be taking along to our next hairdresser appointment.
