I can’t identify her confidently from that description alone. The most likely match from the search results is Claudia Winkleman on The Traitors , since she’s a black-clad woman strongly associated with a game show and has recent coverage of her outfits on the show.

What I can say

  • If you mean a game show host , Claudia Winkleman is the strongest fit from the evidence available.
  • If you mean a contestant or performer dancing on a different show, the description is too vague to pin down one person reliably.

Why it’s uncertain

  • “Woman dressed in black dancing on a game show” could refer to many clips, memes, or TV moments.
  • The results I found point toward The Traitors rather than a uniquely identifiable viral clip.

Best guess

  • Claudia Winkleman is the best guess, but I wouldn’t treat that as confirmed without a screenshot, show name, or clip context.
