Inside Margot Robbie's friendship with BFF: How Barbie girl returned to her native Australia to be bridesmaid for her lifelong pal - as star's friend shares touching 'throwback' pictures of the pair (including from their ballet day

Margot Robbie returned to her native Australia to fulfil the role as bridesmaid for her life-long friend Brittany Claxon last weekend.

The Barbie star, 33, proved she's as down to earth as ever by attending the nuptials in Queensland, showing true commitment to Brittany who attended her own wedding to British film producer Tom Ackerley in 2016.

Brittany, 33, documented her friendship with the Wolf of Wall Street star on her Instagram page, including posting 'throwback' pictures of the pals in their school days.

In one snap - to mark Margot's 24th birthday - she posted a picture of the pair at a ballet class alongside the caption 'been together since I can remember'.

She also posted a snap of herself and Margot, plus two other pals, in their blue tartan school uniform and at a joint birthday party.

A decade ago, when the pair were in their early twenties, they visited the Harry Potter Studio Tour in London, posing with activity passports.

Plus, she also documented their relationship as mature adults, poking fun at Margot's glamorous appearance by claiming the star 'forgot the memo' for a 'casual Monday'. 

Oscar winner Margot, who is now based in the US, is one of the most in-demand actresses in Tinsel Town, but no film role would seemingly stop her reuniting with Brittany for her special day, which turned into a 48-hour bash featuring a raucous Las Vegas themed-party.

Brittany can be heard saying: 'This Barbie Is A Bridesmaid!' as she joined her down the aisle at the event, in which she took on duties including handing the bride a bunch of Calla lilies.

Margot also joined in the celebrations at Rick Shores restaurant alongside the wedding party on day two of the bash.

She slipped on a Barbie-pink mini tutu dress, heart shaped sunglasses and a sash that read 'bridesmaid' while partying into the night at the Las Vegas themed party.

Brittany and Margot were bridesmaids for their other close pal Anna Bryan in 2019, again back home in Queensland, three years after Brittany was in attendance at Margot's wedding to British movie producer Tom held in Byron Bay.

As well as her best friend's wedding, Margot also returned Down Under to attend the 2024 AACTA Awards, hosted by Rebel Wilson, in which she received the Trailblazer Award for her services to the film industry.

The actress touched down in Brisbane after travelling to her home state by herself in February.

Margot - who hails from Dalby, Queensland - was seen stopping to take selfies with fans and visiting a children's hospital during her time in Oz.

Her best pal Brittany is an account manager at Lindores Personnel, her family's recruitment firm which specialises in finding candidates for the jobs in the construction industry.

But away from her day job, Brittany is a keen road racing cyclist and competed at an elite level in Australia, and has also launched her own allergy-free cookbook packed with nutritious meal ideas.

Last year, she raised over £5,000 for charity by running 100km nonstop, where she was supported by her sister.

Her new husband Max is a site manager at Hutchinson Builders, the current project manager of 180 Marine Parade in Queensland which overlooks the Gold Coast.

The couple regularly workout together and have competed in fitness events, regularly showing off their athletic figures on social media.
