Exploring The Challenge: USA contestant Derek Xiao’s romantic relationship with Claire Rehfuss

Claire and Derek fell in love during Season 23 of the hit CBS reality TV show Big Brother. Sparks began to fly after they were evicted and sent to the Jury House. Derek told US Weekly:

“I remember the first or second night that she was there, we stayed up all night just talking until 5:00 a.m. That happened every single night for the first, like, five days”

Claire was the founder and president of her high school’s Engineering club. According to her LinkedIn profile, she holds a Bachelor's degree in Engineering and Data Science from the University of Michigan. Interestingly, she was the “co-president/producer of Survivor: Michigan, a semester-long, on-campus competition based off of CBS's Survivor.”

Claire has been working at Microsoft as a Senior Cloud Solution Architect - AI since 2018. According to her profile on the CBS website, Claire has “written code that’s been on satellites, used in national election campaigns, and by many of the top Fortune 500 companies.” Derek, on the other hand, is the founder of a startup company in New York that delivers meal kits based on recipes from food influencers.

The reality-show power couple made their relationship official weeks after the season finale of Big Brother 23. Claire told US Weekly in October last year:

“I think both of us had like a little bit of a crush, or at least saw maybe there’s some potential there, pretty early on in the game”

Their Instagram profiles feature many adorable pictures of the two. Claire also appeared in Derek’s DX Vlogs.

The couple is also rumoured to be one of the teams participating in the upcoming The Amazing Race 34, but CBS is yet to provide confirmation. For now, it is confirmed that Derek will be seen in the upcoming season of The Challenge: USA.
