90 Day Fiancé star Sophie Sierra’s weight-loss journey has a shocking secret, and it has a lot to do with her now ex, Rob Warne. Sophie is half Jamaican and half British. She grew up in Spain and went to a school where she couldn’t fit in because of her mixed-race background. Sophie did live a life of luxury thanks to her rich grandfather, but she wasn’t happy because she was mistreated and bullied by her peers. Sophie grew up expecting her partner to be mixed-race like her.

When Sophie found Rob on Instagram, they bonded over their shared childhood experiences. Sophie relocated from the UK to Los Angeles where Rob lived a frugal life. He wasn’t able to fulfill Sophie’s needs, although she didn’t have many. Sophie tolerated the apartment without the bathroom and the bed without a comforter, but cheating is where she drew the line. Sophie and Rob separated after she discovered the extent of Rob’s online cheating. They ended their marriage on 90 Day: The Last Resort and Rob is seemingly dating Jeniffer Tarazona while Sophie still seems to be hung up on him.

Sophie Realized Rob Prefers Athletic Women

Did Rob Really Like Bodybuilders?

Rob and Sophie opted for couples counseling to address their trust issues and intimacy problems. Sophie had a hard time trusting Rob, while he was tired of her still not having moved on from the past. Sophie had even tried to dress up for Rob because he was intro costumes. However, Sophie didn’t appear too comfortable with the idea, since she knew Rob was still flirting, receiving naughty pictures from women and telling them that they looked really beautiful. Sophie observed the women Rob flirted with didn’t look like her.

“They don’t look like me, like, muscular fitness bodybuilder women. I don’t look like that.”

Rob was upset with Sophie exposing him. He told her that he was into “fitness chicks” because “bodybuilder women” was like some “fetish, deviant sh**.” Rob maintained that he did not belong to the category of men who liked bodybuilder women. He did not have that kind of fetish. However, Sophie told the producers that Rob was lying since the women he sought out were “pretty muscular.” They were “serious,” fitness muscular women that one doesn’t just see walking around. When caught, Rob told her he was saving their photos for fitness inspiration.

Sophie Flaunted Her Weight Loss On Instagram

In October 2024, Sophie did a Q&A session with her Instagram followers. One of her fans was interested in knowing if Sophie had lost any weight because she had started looking very slim in her recent photos and videos. Sophie replied saying she had dropped some weight since she did 90 Day Fiancé: Happily Ever After? season 8 with Rob. “Since the show I lost around 17 lbs.” Sophie proved her point by sharing a picture of herself after the weight loss.

Sophie’s new hair color is her natural one. She had damaged her hair by bleaching it and straightening it and, hence, had to wear wigs on the show. Now, Sophie has embraced her dark hair, which is voluminous, with the help of extensions. It takes a few pounds off Sophie’s face, which already looks so much smaller after weight loss. Sophie’s chin is pointed with a sharp jaw and a narrow nose. Her waist is tiny in the picture, highlighted by the two-piece outfit consisting of a floral bra and skort.
