Chloe and Zoey are Nikki's best friends and they both dislike Mackenzie because she's so vain and mean. She helps out Nikki from horrible situations, usually caused by Mackenzie. They used to like two CCP's, Jason and Ryan, which ended at the 3rd book, although Nikki still thinks their crush on them still lives on, in the 6th book. They are very kind and helpful.
