Austin Butler can't fit into his Celine trousers after bulking up his butt for Caught Steeling

Austin Butler can no longer squeeze his butt into his designer Celine pants since bulking up for Caught Stealing.

The 34-year-old actor underwent a major body transformation to portray basketball player-turned-bartender, Hank Thompson, in the 2025 American crime thriller film, packing on 15 kilograms.

He told Men's Health magazine:  “I actually have a whole section of just baseball players’ asses that [director, Darren Aronofsky] would send me.

“He was like, ‘Look how thick they are!’”

And while he has an enviable body, he was left gutted to no longer be able to fit into the expensive pants, adding: “I’ve got a whole section of Celine pants that I just can’t even wear anymore.”

Austin was assigned personal trainer Beth Lewis, who got Hugh Jackman beefed up to portray Marvel's Wolverine.

It's quite the contrast to having to pile on the pounds to portray Elvis Presley.

Austin drank microwaved ice cream and dozens of doughnuts for his Golden Globe-winning portrayal of the late King of Rock and Roll in Baz Luhrmann's 2022 biopic Elvis.
