Sweeney's longtime hairstylist Glen "Coco" Oropeza fired back when critic Blakely Thornton said her recent look was a wig

If there’s one thing about Sydney Sweeney, it’s that she’s not afraid to go against the grain. This year, the Euphoria star swapped her iconic tumbling golden locks for a chin-scraping bob, debuting the look a few weeks after her 28th birthday.

Its ad campaigns not only whipped up controversy but have propelled American Eagle sales and growth, while it has confirmed Martha Stewart as its new holiday season face.

Sweeney previously debuted a blonde bob at the AFI Fest screening of 'Christy' in Los Angeles on Oct. 25

The 28-year-old is in contention for the best actress Oscar for her portrayal of trailblazing boxer - and domestic abuse survivor - Christy Martin in David Michôd's new film.

American Eagle raises outlook for the holiday quarter and the year on ‘strong momentum’ for sales.

Sydney used the breathtaking setting of Sydney, Australia, to establish a compelling new world for the franchise.

For the red-carpet event, Sweeney slipped on a custom Miu Miu gown in an electric silver, covered entirely in little clear crystals that shimmered in the spotlight. The dress had a halter tie and a deep, plunging neckline that showed off her cleavage.
