12society.com was launched on Tuesday (12Jun12) and is aimed at turning members into tastemakers with monthly packages full of the stars' favourite items and the latest fashionable products, like headphones, sportswear and gadgets.
Subscriptions are priced at $39 (£24)-a-month, and fans will receive regular deliveries worth at least $125 (£78) and access to exclusive online content.
Nas tells MTV.com, ""With 12 Society you don't have to just listen to me talk about a certain s**t (sic), you'll get that delivered to you.
""To me the 12 Society thing is just people like myself and other people that are involved connecting with the people. Giving them some insight on our lifestyle and making the people a part of it... What you're receiving is worth way more than what you're paying for. This is for everybody; this is not for rich people. This is for everybody. It's a cool thing.""
Basketball stars Blake Griffin and Kevin Love are also investors in the website venture.
