VIP Brother is a Bulgarian reality television game show in which a number of celebrity contestants live in an isolated house trying to avoid being evicted by the public with the aim of winning a large cash prize or collecting money for charity.

In 2012, it was announced that Nova TV had closed a deal with Endemol for two seasons of the Big Brother format in Bulgaria.

In September, VIP Brother 4 aired lasted for 63 Days (the longest celebrity season so far) and immediately followed by an all-star's edition.

Like the original Big Brother, VIP Brother is a game show in which a group of celebrities, called the Housemates, live in isolation from the outside world in a house, which includes everyday facilities such as a fully equipped kitchen, garden, bedrooms, bathrooms and living area.

The only place where housemates can escape the company of the other contestants is the Diary Room, where they are encouraged to voice their true feelings.

The two, or more, Housemates with the highest number of nominations face a public vote conducted by phone (text messages).
