Claire Rehfuss, the former contestant from Big Brother, is straight-up denying the cheating allegations against her ex, Derek Xiao. Recently, social media lit up with claims that Derek cheated on her with a coworker shortly after they broke up. In a bold move on X, Claire shared evidence of these rumors while blasting the online harassment they’ve faced since leaving the show.
She firmly stated, “Derek didn’t cheat,” urging followers not to engage with the online haters spreading false claims and hateful comments, resonating with her frustration over the situation. After four years together and a shared win on The Amazing Race, the couple decided to part ways in September 2025, amicably citing they’re simply different people now. Claire has since channeled her energy into personal hobbies, showing that sometimes you can come out stronger after heartbreak, no matter the rumors.
It’s a reminder that reality TV relationships aren’t just scripted drama; they come with real emotions and challenges. So, what does it take to keep your head up while navigating those turbulent waters?
