Even Brad Pitt is tapping into the Y2K trend.

Just as low-rise jeans and baby tees are making a comeback, so is one of the Once Upon a Time In Hollywood star's most iconic looks of the 2000s.

Ditching his signature blonde locks, Brad was recently seen driving around Los Angeles while sporting a clean buzzcut similar to the one he rocked during the early aughts. And just like his Tyler Durden character in 1999's Fight Club, the 61-year-old capped off the look with large sunglasses.

While Brad has undergone many hair transformations throughout the years, his buzzed head is possibly one that stands out among the rest. After all, his then-girlfriend Jennifer Aniston was the one who shaved it all off for his role in Fight Club.

The Oscar winner went on to grow his hair out in the time for the film's October 1999 premiere—as well as his July 2000 wedding to the Friends actress—before shaving it all off again during the mid-aughts to film 2005's Mr. & Mrs. Smith, where he met his second wife Angelina Jolie. (They split in 2016.)

But these days, Brad's style is centered more around practicality. "You get older, you get crankier, and comfort becomes more important," he quipped to Esquire in 2021. "I think it’s as simple as that."

And he doesn't want to hide his age, either.

"I don't want to be running from aging," he said in a 2022 interview with Vogue. "It’s a concept we can’t escape, and I would like to see our culture embracing it a bit more, talking about it in those terms."

Describing "anti-aging" as "ridiculous," Brad continued, "I think that we’re learning that if we love ourselves, if we treat ourselves a little better, then there are long-lasting benefits to that. So just age healthy, age in a healthy manner."
