While many fans have been focused on Patrick Schwarzenegger’s role in Season 3 of The White Lotus, Arnold Schwarzenegger’s middle son, Christopher Schwarzenegger, has quietly made headlines for a different reason. In April 2025, Christopher revealed a striking weight loss transformation when he posed for a photo with his siblings Katherine, Christina, and Patrick. Katherine shared the picture on Instagram with the caption, “My favorites forever and always,” and tagged it with “National Sibling Day.”
In the photo, Christopher stands on the left, looking noticeably slimmer and fitter. He is almost unrecognizable compared to images of him from 2019. Though he is the youngest brother in the group, Christopher appears to be the tallest, standing even taller than Patrick and his sisters. Christopher has faced personal challenges, including body shaming from a young age. Despite these hardships, he has shown great resilience and clearly come through stronger.
This recent weight loss is not Christopher’s first noticeable transformation. In 2023, photos surfaced online showing him much slimmer, which caught public attention. Unlike his siblings, Christopher tends to avoid the spotlight, so it was refreshing to see him out and about. Recently, he showed support for Patrick by attending the Los Angeles premiere of The White Lotus Season 3 alongside his family.
One notable absence from Katherine’s “National Sibling Day” post was their youngest brother, Joseph Baena. Joseph is actually their half-brother, born from Arnold Schwarzenegger’s affair with his former housekeeper, Mildred Baena. Katherine later disabled and deleted comments on the post after some users noticed similarities between Christopher and Joseph, especially before Joseph started bodybuilding. One comment noted how close their ages are, being only about five days apart.
In 2023, Page Six reported that the four Schwarzenegger siblings did not have a relationship with Joseph Baena. A source told the outlet that while Arnold treats all his children fairly, the other siblings do not get along well with Joseph. The source explained, “To be honest, the other kids don’t love Joe. It’s a shame because he’s a really good kid. Arnold has always treated him like the others, but for some reason, the other kids take [the affair] out on Joe.” Although this was reported two years ago, Joseph’s absence from the recent family photo highlights the ongoing tension between the siblings.
