Nikki and Pete were both as fake as each other over their supposed romance.

Nikki jumped on the "I love bandwagon" when she heard most of the other housemates (i.e. Sezer and George) state that Pete was going to win. She knew that a romance with Pete would help her financially.

Pete suddenly fell in "love" with Nikki when she was evicted. Or did he reason that Nikki got all those cheers when she was evicted because she was very popular and that she had been evicted because people were sorry for her and he would be less liked now because he had hurt Nikki by flirting with Aisleyne in front of her.
