Christopher Schwarzenegger looks unrecognizable in new family snapshots.

In a collection of getaway photos shared by sister Katherine Schwarzenegger on Friday, Christopher, 27, showcased his dramatic weight transformation in a summer-ready ensemble of a fitted button-down shirt and pink shorts as he checked his smartphone.

Other photos showed family members — including mom Maria Shriver and Katherine’s husband, Chris Pratt — enjoying time on a boat in Cape Cod.

“A perfect day ☀️🌊,” the mom of three, 35, captioned the sunny carousel.

Christopher previously showed off his lean new look in June, when he joined dad Arnold and siblings Christina, Patrick and Katherine for the Season 2 premiere of “FUBAR” in Los Angeles.

In May, the University of Michigan grad spoke out about the weight loss transformation while attending Beacher Vitality’s Happy & Healthy Summit in Los Angeles.

“It was a big process,” he said during a panel, per People, explaining that he began modifying his lifestyle when he was living in Australia back in 2019.

“I just saw how much my weight was prohibiting me from doing the everyday activities,” he shared with the panel — which included Kelly Osbourne, who’s had a physical transformation of her own.

“I was like, ‘I want to go skydiving,’” he recalled. “And my friends were like, ‘Yeah, no shot,’” to which he agreed.

“I was like, ‘Yeah, I can’t skydive,’” he recalled.

Christopher also divulged that his body image issues stretched back to high school. “I tried everything,” he said at the time, adding that he was “doing meal delivery things in high school.”

He said he remembered “feeling like a weirdo when I was bringing weird lunches to school.”

Christopher shared that his gradual weight loss was “not an overnight thing,” adding that it “took a lot of trial and error.” A fitness regimen and diet changes were among his strategies for an overall healthier lifestyle.

Christopher divulged that he “gave up bread for Lent” — which lasts 40 days — and lost “30 pounds just through that.”

He also reflected on “before and after photos” of his physical changes. “I don’t feel like I’m an ‘after’ yet,” he confessed.
