With his well-tailored suits and long wavy hair, Justin Trudeau was often hailed as the best dressed man in the world of politics. But since resigning as Canadian prime minister the 54-year-old has undergone a whirlwind transformation, going from polished premier to letting loose with girlfriend Katy Perry. The couple made their relationship status official late last year and in the short time since Trudeau has quickly adjusted to being the boyfriend of a popstar. In November he flashed a tattooed bicep as he posted a selfie to his 4.6million Instagram followers urging them to get a flu jab.

He wrote: 'Got my flu shot and COVID-19 vaccine today. It's a simple way to protect yourself, your loved ones, and our health care workers. If you haven't gotten yours yet, book it today at your local pharmacy or clinic.' But while some thought the former politician's new look was 'cool', another joked: 'This is the picture he sent to Katy Perry for sure.' Trudeau further showcased his style transformation over the weekend, as he was pictured at Coachella with the 41-year-old singer. The former Canadian prime minister dressed casually in a white t-shirt and blue jeans, which he paired with a pair of grey trainers and a navy cap which he wore backwards. Meanwhile, Perry wore a bold slogan t-shirt which read: 'Please do not give me a rip off your vape no matter what I say' while posing with a cigarette behind her ear. Once again, shocked onlookers remarked on Trudeau's new lifestyle, saying: 'Seeing your ex-prime minister in a club is so wild' and 'No stress looks good on you, Justin.'

Although Trudeau has let go of the prestige he held for a decade as Canada's prime minister, it's clear he's wasted no time capitalising on his image to transition to full-time Instagram influencer. Three days after passing the torch to Mark Carney last year, Trudeau posted a selfie that showed him stocking up on household items at a popular department store. The picture showed him carrying a trolley full of kitchen items, including a Master Chef cordless electric kettle and a hand mixer. Commenters acknowledged the stark difference in his revamped look. 'Just a normal Canadian dude shopping for kitchenware now,' read one remark under the post. Another noted: 'Looks like he is setting up his bachelor pad.' Trudeau's popstar girlfriend has also had to change up her wardrobe due to his political commitments. Perry ditched her usual aesthetic for a demure look as she accompanied the former Canadian prime minister to the World Economic Forum in Davos in January.

The singer, with her hair slicked back in a bun, opted for a scoop-neck cardigan with balloon sleeves and a matching pencil skirt from luxury Paris brand Jacquemus - in stealth wealth beige. Her accessories, including drop earrings from The Care, were similarly pared back. But Perry still showed her cheeky personality when she winked at her boyfriend during the event. She joined The Female Quotient lounge to support Trudeau as he gave his speech. Perry left Trudeau grinning from ear to ear when she caught his eye from across the room.

In a clip shared to Instagram, Female Quotient wrote: 'The room was packed, the energy was high and Katy kept it low-key, cheering them on. A reminder that showing up matters.' Trudeau was joined on stage by his former chief of staff, Katie Telford, to discuss women and underrepresented voices. The couple, who first sparked dating rumours in July last year, have since forged a firm bond and are frequently spotted out and about on lavish jaunts.
