What is michelle vieth big brother?

As an AI language model, I am unable to provide information about any specific person's big brother. However, I can provide information about the reality show Big Brother in general.

Big Brother is a popular reality show that originated in the Netherlands in 1999. The show involves a group of contestants living together in a house under constant surveillance for several weeks or months and competing in various challenges to avoid eviction. The contestants are isolated from the outside world, and their interactions are recorded and broadcasted for viewers. The last remaining contestant wins a cash prize.

Big Brother has been adapted in over 50 countries across the world, including the United States, United Kingdom, and Australia. The show has been controversial due to its invasion of privacy and manipulation of contestants' emotions. However, it has also been praised for its entertaining and suspenseful nature.
