Just when they thought there were no more surprises, the housemates are in for the shock of their lives when six new intruders enter the house this week.

And identical twins Charlotte and Alex, 26, are sure to have everyone doing a double take when they arrive, thanks to their matching blonde locks and bubbly personalities.
However, they aren’t to be underestimated, because these Melbourne-based sisters tell New Idea they already have a few tactics to remove the other housemates from the game and win the top prize.

“I will be a strategic mastermind,” teases Alex.
“I have a few strategies up my sleeve and I think the housemates won’t expect it, so I will just let them believe that, but my brain is always pondering.”
And the housemates better be honest with the twins, because Charlotte says she absolutely can’t stand “liars”.

Alex is thrilled to be joining the show this season – and appearing alongside her sister is even better!
Plus, it’s their last chance to spend some quality time together before Alex moves out of the family home to live with her boyfriend.
“My sister is moving out after this,” says Charlotte.
“So we thought what better way to celebrate and make memories than in the Big Brother house.”

Should one of the twins win, they plan on splitting the prize money.
And with Alex’s half, she reveals that she’s planning to “treat myself to something special and then put the rest towards my mortgage or getting an investment property”.
Meanwhile, Charlotte will “use part as a house deposit and then go on a tropical holiday”.
