<P> Celebrity Big Brother (or Big Brother VIP) is an adaptation of the Big Brother reality television series franchise in several countries, in which the housemates are local celebrities . In some countries, the prize money normally awarded to the winning housemate is donated to a charity, and all celebrities are paid to appear in the show as long as they do not voluntarily leave before their eviction or the end of the series . The rest of the rules are nearly the same as those of the original version . </P> <P> The celebrity version has become particularly popular in the UK, causing UK broadcaster Channel 5 to extend its deal with Endemol enabling them to air two celebrity series in addition to the civilian version every year from 2012 . As of 2017 the UK has aired 20 celebrity series with the current Celebrity Big Brother 20 from 1 August 2017 . In Bulgaria, VIP Brother has replaced the original format of the show and more seasons of the celebrity edition have been produced than the regular one . Due to the show's popularity there, it lasts for two months unlike most countries where it only airs for a month . </P>
