The trio of personalities were originally rejected from the show for being too “over the top”.
They include an “Indian Brian Dowling”, a Dr Who fan and a girl nicknamed The Hurricane.
Viewers will be invited to vote for their favourite during launch week, with only one entering the house to become a housemate.
Bit On The Side star Jamie East was given the power to pick the wild card finalists from the hundreds of rejected auditionees.
He told the Daily Star today: “I went in with a plan to pick housemates that Big Brother would never put in the house.
“I think I’ve succeeded.”
He went on: “I am so confident with my choices.
“I predict that whoever viewers choose will go all the way and make the final.”
The trio will star in a special audition show at 8PM on June 5 on Channel 5, before the live launch show at 9PM.
