Olivia Rodrigo has embraced Australia’s iconic brand Vegemite, adding a cheeky local twist to her wardrobe as she took the stage during her Guts world tour.

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

She sported a stylish T-shirt with the slogan ‘Vegemite just be in love’ while she belted out her hit Good 4 U during her third Melbourne show on her Aussie tour.

It isn’t the first time Olivia has given a nod to Aussie culture as she has already tried out Tim Tams in an amusing TikTok video.

On her opening night in Melbourne, she also sported a tank top with the phrase ‘Bad Idea, I reckon?’ – a playful twist on her hit track Bad Idea, Right? and a fun reference to Australia’s laid-back lingo.

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 Aussie catchphrase.

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

Olivia has been making the most of her time Down Under and even filmed herself tucking into an original Tim Tam  for the first time.

In a TikTok video, she sat cross-legged in her hotel suite while being surrounded by six packets of various flavours as she fully embraced the tradition. 

‘Spectacular, give me 14 of them,’ the audio on the clip narrated.

She also sent fans wild when she visited well-known Melbourne star Pesto the penguin at Sea Life Aquarium during her time in the city.

The King Penguin has become famous for his impressive size of 23kg and eating 25 fish a day, with videos of him racking up millions of views.

Taking to Instagram on Friday, the pop star shared photographs and videos of her visit with the now-viral marine bird as Pesto nabbed yet another celebrity fan.

Dressed in snow gear and goggles, Olivia – who is currently Down Under for her Guts world tour – looked delighted as she met the famed penguin in a sweet moment.

She also shared a video of herself smiling and flashing the peace sign as nine-month-old Pesto – who is an impressive 90cm long – stood beside her.

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

Animal lovers around the world have been left stunned by the astonishing size of Pesto, a penguin chick who weighs a whopping 23kg.

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

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

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