Arnold Schwarzenegger's son, Christopher Schwarzenegger, is showing off his dramatic weight loss once again, this time while being spotted with a mystery woman in photos shared by his sister Katherine Schwarzenegger Pratt.

Just last month, Christopher had already made waves when he revealed his slimmer figure during a family vacation, giving fans a look at his ongoing transformation.

Christopher, one of four children Arnold Schwarzeneggershares with ex-wife Maria Shriver, revealed that his decision to take his health more seriously began five years ago.

Katherine's series of family photos on Instagram highlighted her younger brother's new look and what may be a new relationship. Christopher appeared noticeably slimmer as he joined his family for a day outdoors. But it was not just his weight loss that had people talking. 

In one of the photos, Christopher was seen with his arm around a blonde woman sitting on his lap, sparking buzz about a possible girlfriend.

Other shots from the slideshow showed the 27-year-old shirtless with a tan, flexing his toned arms while pointing off into the distance. The family gathering also featured Katherine's husband, Marvel actor Chris Pratt, as well as one of their three children.

This recent moment marks another public appearance for Christopher's slimmed-down frame, which is steadily becoming more noticeable. Last month, The Blast pointed out that he looked very different as he joined his loved ones for a day out on the water.

In the set of photos, Christopher relaxed on a boat in a sky blue button-down shirt paired with pink shorts while scrolling on his phone aboard a boat.

The family trip also featured their mother, Maria Shriver, Katherine, and her husband, Chris Pratt, who was also photographed taking a dip in the ocean with one of their children.

The 'FUBAR' Star's Son Opens Up About The Turning Point In His Weight Loss Journey

Speaking at the first-ever Beacher Vitality Happy & Healthy Summit in Los Angeles, Christopher explained that the change began in 2018 during a trip to Australia when he realized his weight was holding him back from enjoying everyday activities. 

One of the biggest wake-up calls came after a failed skydiving attempt that left him determined to turn his life around. He admitted that his first major step was giving up bread for Lent. Sticking to that simple commitment helped him shed 30 pounds. In his words:

"And that was my one rule. I was like, 'I'm not going to break Lent.' And so I lost 30 pounds just through that."

Christopher may be the son of Arnold Schwarzenegger and Maria Shriver, but he is carving out his own journey away from the Hollywood spotlight. 

According to E! Online, the associate producer holds the role of Vice Chair on the Special Olympics Founders Council, an organization created by his grandmother, Eunice Kennedy Shriver.

Outside of his nonprofit work, Christopher is building a career in entertainment. He serves as Director of Development at Los Angeles-based production company Indus Valley Media and has previously worked with content agency Malka and renowned sports psychologist Trevor Moawad.

A 2020 graduate of the University of Michigan with a degree in psychology, Christopher has kept most of his life out of the public eye.

However, he occasionally steps into the spotlight, joining his family on red carpets, including his father's Netflix series "Fubar" premiere and the screening of his brother Patrick's season of "The White Lotus."

The actor's wedding to longtime partner Abby Champion was a star-studded family affair in northern Idaho, but one person missing from the guest list was his half-brother, Joseph Baena.

The Blast highlighted that Joseph, the son Arnold Schwarzenegger welcomed with the family's former housekeeper Mildred Peña, did not receive an invitation to the big day.

Sources told TMZ that Joseph was not included because he does not have much of a relationship with Patrick or his other half-siblings. His absence did not come as a shock, given the complexities surrounding his place in the family since the affair came to light in 2010. 

Christopher Schwarzenegger is stepping into a new chapter of his life as he continues to make strides in his weight loss journey.
