Nikki’s obsession with smelling everything hasn’t gone unnoticed by the rest of the house, even the newcomers.

Sam picked up on Nikki’s sensitive nose within 24 hours of being in the house, telling the 24-year-old model/dancer that she reminded her of Kim and Aggie, stars of Channel 4’s How Clean is Your House

Nikki is more than aware of her nosey habit. "The first thing I do when I get a present is take it out and smell it," she said.

However, Nikki doesn’t always smell nice things - and nor do the rest of the housemates, who are being plagued by someone's foul emissions.

"It wasn’t me last night," screeched Nikki, "but I’ve done a couple of sneaky ones."
