Arnold Schwarzenegger's Son Is Seriously Unrecognizable After Weight Loss Transformation

While everyone has been swooning over Patrick Schwarzengger on Season 3 of "The White Lotus," people have been sleeping on Arnold Schwarzenegger's middle son: Christopher Schwarzenegger. Christopher showed off his massive weight loss in April 2025, when he posed with his siblings: Katherine, Christina, and Patrick Schwarzengger. "My favorites forever and always," Katherine captioned her family group snapshot on Instagram. She added the hashtag, "National Sibling Day."

Standing on the left is Christopher, looking slimmed down and fit. He's practically unrecognizable from the guy in the paparazzi photos from 2019. He may be the little brother of that group, but he's definitely the tallest, towering over his sisters and even looking slightly taller than older brother Patrick. Christopher has suffered tragedies in his life, including dealing with body shaming from a young age, but he's persevered and has clearly come out on top.

This isn't the first time he's had a drastic weight loss. Christopher turned heads in 2023 when photos hit the interwebs of him looking much slimmer. Considering how he tends to avoid living his life in the spotlight, unlike his siblings, it was nice to see the youngest Schwarzenegger out and about. More recently, Christopher celebrated Patrick's success by attending the LA premiere of Season 3 of "The White Lotus" with his family.

Katherine Schwarzenegger's "National Sibling Day" post was missing one key element: her and her siblings' youngest brother, Joseph Baena. He is actually their half-brother, born from Arnold's affair with his housekeeper, Mildred Baena. Though Katherine seems to have since disabled (and deleted) comments on that specific Instagram post, Page Six reported one person had previously written, "Christopher looks a lot like Joseph, especially before Joe got into bodybuilding and they are about 5 days apart wow."

The outlet published an exclusive back in 2023 that claimed the four Schwarzenegger siblings didn't have a relationship with Baena. A source told the publication: "To be honest, the other kids don't love Joe. It's a shame as he's a really good kid, and Arnold has always treated him like all his other kids — very fairly. But for whatever reason, the other kids take [the affair] out on Joe." While that was two years ago, the fact that Baena is missing from the sibling snapshot speaks volumes about the relationship between the five brothers and sisters.
