Biannca could be seen flashing her breasts while giving Helen Wood a sexy dance in the garden area of the house on Wednesday's edition of the show.
As another new arrival, Zoe, performed a sexually-charged song to the housemates, Biannca unzipped her jumpsuit and started writhing around in Helen's lap.

And Wood certainly didn't seem flustered by the event, even leaning in so that she could touch her fellow housemates exposed breasts.
After Biannca finished her dance, Helen grabbed her fellow housemate's bosom, saying: 'Oh my god! I'm jealous!'
But despite flirting with former call girl Helen, Biannca only really had eyes for male housemate Winston, who she described as 'pretty,' admitting that she would like to 'f*** your brains out.'
