Karly and Sophie played their own practical joke on the male housemates today, telling them that they had previously worked together on a porn movie.

The pair of glamour models tried to convince the group that they starred in a movie titled ‘She’s the t***, I’m the a***.’

Karly then stroked Sophie’s arm, saying: “We’re lesbians.”

Sophie added: “Lesbian porn stars. Well, bisexual. We’d try a man.”

“Sometimes we just stay in bed and have sex all day. With each other.”
