Justin Bieber has always been at the forefront of fashion. Starting off at a young age with his "Baby" era, we've not only watched his career skyrocket, but we've also had the pleasure of seeing his sense of fashion grow and evolve as he's gotten older.

Celebrity style has been on our minds for a while now, whether it is Cardi B in Schiaparelli, Bella Hadid's impressive sneaker collection, Steve Harvey's zaddy era, or Pete Davidson's effortless scum bro aesthetic. Up next, is another look at J-Biebz himself.

Recently, the singer took a page from Kanye West's style book, sporting Balenciaga's chunky Croc Boots at Ye's Sunday Service, but his most recent reference comes from somewhere else.

For his wife Hailey Bieber's birthday, Justin got dressed in a white tee, long leather jacket, black trousers, and a beanie – and he looks straight out of the Backstreet Boys. If you photoshopped him onto the cover of Backstreet's Back, or even Backstreet Boys, we are sure nobody would be able to tell.

Meanwhile, Hailey Bieber wore a bodysuit from Anthony Vaccarello's Saint Laurent, to celebrate her 25th birthday alongside friends including Kendall Jenner, Jaden Smith, and more.

Clearly, Bieber is a fan of the ever-growing Y2K trend, rocking oversized jeans (the rise of JNCO) court-side, denim dungarees at the MTV VMA's, and trucker caps paired with a surprise appearance from Bottega Veneta.

Justin isn't the only Bieber with an affinity for the 2000s – Hailey also brought us back to the naughties for Halloween, where she recreated not one, but four iconic Britney Spears looks from the decade. She also revealed a Princess Diaries look on Instagram, which is a true classic for any '90s baby.

There's no doubt that Justin Bieber's style is ever-changing, and with Hailey by his side, the two have proven to be the most effortlessly stylish couple that we can't help but love.
