Cast your minds back to two years ago when Amy and Sally were brought into the show in February 2013 at the beginning of series eight.
Their arrival was quite dramatic as it rocked Lucy Mecklenburgh and Mario Falcone's romance at the time.
Amy claimed TOWIE star Mario tried to bed her after a night out in Manchester, but Mario strenuously denied these claims.
Amy and Sally, who were also 'Sugar Hut Honeys' at Mick Norcross' Essex nightclub, were only seen in a few episodes and were not featured again.
The new series of Big Brother: Timebomb kicks off on Tuesday (12 May) and the twins will enter the compound with 15 other housemates.
In a new twist and a first for the show, producers decided to unveil the new batch of housemates before they actually entered the house! Will Amy and Sally talk about their brief stint on TOWIE while in the house?
Show bosses have promised this series of Big Brother will be "upbeat, glamorous, thrilling and mischievous"!
Big Brother Live Launch on Tuesday 12 May at 9pm on Channel 5.
