The current Miss India UK was randomly selected as the first housemate to enter, after Brian Dowling had promised that a twist was in store for her.
Before entering, the 23-year-old was informed that she would be granted immunity from the first week of evictions.
However, she was then told that this immunity would come at a price.
She is to nominate three housemates for eviction at the end of tonight's show based on her first impressions of them.
The model has claimed that the greatest love of her life is money, and entered the house at the beginning of tonight's premiere to a mixture of cheers and boos.
