Olivia Rodrigo makes an unexpected cheeky nod to Aussie culture with her wardrobe during Melbourne concert

Olivia Rodrigo has embraced iconic Australian brand Vegemite and added a sassy, ​​local twist to her wardrobe as she took to the stage during her Guts world tour.

During a performance at Melbourne’s Rod Laver Arena on Sunday night, the 21-year-old pop star made waves with a quirky tank top with a Vegemite-themed message.

She wore a stylish T-shirt with the slogan ‘Vegemite just be in love’ as she performed her hit Good 4 U at her third show in Melbourne during her Aussie tour.

It’s not the first time Olivia has given a nod to Australian culture, as she has already tried out Tim Tams in a funny TikTok video.

On her opening night in Melbourne, she also wore a tank top with the phrase “Bad idea, I guess?” – a playful twist on her hit Bad Idea, Right? and a nice reference to Australia’s relaxed slang.

She kept the theme going on night two, stepping out in a crop top emblazoned with the word “Crikey!” – a shout-out to the quintessential Australian slogan.

She will take the stage again for her final show in Melbourne on October 14, before her highly anticipated shows in Sydney at the Qudos Bank Arena on October 17, 18, 21 and 22.

Olivia has made the most of her time Down Under and even filmed herself in an original Tim Tam for the first time.

In a TikTok video, she sat cross-legged in her hotel suite while surrounded by six packages of different flavors, fully embracing the tradition.

“Spectacular, give me fourteen,” reads the audio accompanying the clip.

She also drove fans wild when she visited renowned Melbourne star Pesto the penguin at Sea Life Aquarium during her stay in the city.

The King Penguin has become famous for growing at an impressive 23kg in size and eating 25 fish a day, with videos of him being viewed millions of times.

The pop star took to Instagram on Friday to share photos and videos of her visit to the now-viral seabird as Pesto nabbed yet another famous fan.

Dressed in snow gear and goggles, Olivia – who is currently Down Under for her Guts world tour – looked thrilled to meet the famous penguin in a sweet moment.

She also shared a video of herself smiling and showing the peace sign as nine-month-old Pesto – who stands a whopping 3 feet tall – stood next to her.

Her visit to see Pesto came weeks after Katy Perry boosted the penguin’s viral fame when she visited him ahead of her headlining performance at last month’s AFL Grand Final.

Animal lovers around the world are stunned by the astonishing size of Pesto, a penguin chick that weighs a whopping 23kg.

Its fully grown parents Tango and Hudson weigh 11 kg and 12 kg respectively, while the average size of an adult king penguin is 14-17 kg.

When Pesto was born in January, he already weighed 200 grams and has grown rapidly since then, partly thanks to his enormous appetite.

He eats four times a day, and one meal consists of eight fish. His size has made him an internet star worldwide, with videos of the big chick seen by billions of people.
