Three new female housemates are set to join Big Brother – a model who appeared in a Lynx advert, a ‘sexy executive PA’, and a theatre director.

The trio will not be revealed until they enter the house, after either Jennifer Clark or Rex Newmark is voted out.

Housemates have been speculating about whether newcomers will join them following the producers’ decision to throw out Alexandra De Gale and dance teacher Dennis McHugh.

Dennis was ejected after spitting in Mohamed’s face during a group row.

Alexandra was booted off the Channel 4 show after allegedly threatening housemates with punishment from ‘gangster friends’.

A Big Brother spokeswoman said the three new housemates will be unveiled during an extended programme.

She said that ‘a sexy executive PA, a theatre director in her 40s and a model who has appeared in a Lynx advert’ will join the show.
