Mel knows exactly who her friends are - very gorgeous Amy and very cool Aimee. Collectively, they're known as 'The Amys'. And if you're not in 'The Amys', you're nobody.

Carrie, Alex, Sky, Sam and Jordan are truly best mates. They'd rather get on with having fun than waste time being nasty about everyone else.

Then Mel starts thinking that Carrie and Co. aren't so bad after all - and Carrie can't believe it when Jordan starts hanging out with 'The Amys'. Suddenly, friendship seems a LOT less simple.
