Margot Robbie brought her little brother to the BAFTAs in London

Margot’s incredibly handsome little brother Cameron Robbie made his red carpet debut at the BAFTAs – and judging by his Instagram Story, he had a blast.

We’re used to being wowed by Margot Robbie’s stunning red carpet looks, and while her BAFTAs gown didn’t disappoint – she wasn’t the only Robbie who turned heads.

The powerhouse Hollywood starlet followed the likes of Brad Pitt in opting to bring a relative along to an awards ceremony, attending the BAFTAs in London with her little brother on her arm.

Cameron Robbie – a budding actor himself – bears a striking resemblance to his famous big sis, looking suave and at-home in a black velvet tux which complemented Robbie’s black lace number.

Margot, 29, was nominated twice in the Best Supporting Actress category for her roles in Bombshell and Once Upon a Time in Hollywood.

While she was beaten by Laura Dern, 52, who won for her role in Marriage Story, the Australian actress still took to the stage to give an acceptance speech.

Margot accepted the award for Best Supporting Actor on behalf of her Once Upon a Time in Hollywood co-star Brad Pitt, who was absent.

Reading a pre-prepared speech, Pitt’s cheeky joke via Margot about Prince Harry’s move to Canada prompted laughter from Prince William and Kate Middleton in the audience.

“He says he is going to name this (award) Harry because he is really excited about bringing it back to the States with him. His words not mine,” Margot said.

Judging by his Instagram Story, 24-year-old Cameron had a blast.

Posting from an after-party late in the night, he was seen holding Pitt’s mask-shaped statue up to his face.

The Robbie siblings have long been tight-knit.

In a June 2018 interview with OK! Australia, Cameron spoke fondly of his relationship with Margot.

“We text constantly, and I get to see her a lot on the down-low, which is quite nice. If no one knows she’s in town!” he said.

“She’s always been a good big sis to me, we love to have a lot of fun. I’m really proud of her.”

Cameron, who models as well as acts, made his runway debut at last year’s David Jones Autumn/Winter’19 launch, held at Hobart’s Museum of Old and New Art.

However, his sights are set on following in his sister’s footsteps, calling himself “an actor first, a model second”.
