It isn't much, but it was enough to convince fans she might be the winner. After all, how could she continue in current tense to stare into Richie's eyes if she wasn't the winner? Suspicious.
Nikki also revealed that Richie is such a good kisser, she had to go back for more on separate occasions.
“The first one was so good, I had to go back for more,” she said.
"I didn’t want to waste any time with him," she revealed of their first date. "I was very aware that there were 18 gorgeous girls back at the mansion at that point. I did the maths and thought ‘Right, my next individual date isn’t going to come around quickly’.
"Afterwards we were giggly," she said. "Then we got a bit shy."
Time will tell if her slip really means she's the winner!
