Where are my contacts in Mail app in ML?

I can't find them. I've googled and see that there is mention of the address book. Where's that? Nothing like that in the applications folder here.

I've synched my Blackberry with the laptop and can find neither the phone's contacts or my email contacts

In Mountain Lion - they renamed Address Book - to Contacts. iCal is now Calendar. There are also Reminders, Notes, and Mail to finish of all the PIM functions. It is to make it match the names in iOS so that people switching -> who have iOS -> will have a familiar name.

Doh! I was too busy looking for something called Address Book.
Thanks IvanLasston, I see them now!
