I dont know if anyone else has spotted this yet , but there was a nice little article in one of todays mags (possibly reveal) about Nikki's visit to that sick little girl in Scotland.
There was a picture of them both ,and they said that she spent the whole day with her going shopping and buying her some nice little outfits. And then she took her to the chitty chiity bang bang show along with the girls parents.
The little girl said Nikki was her favourite housemate because she was funny and made her laugh ,and she stopped watching when she was evicted.
