My So-Called Nip Slip

The TMZ Nip Slip Society welcomed its newest member yesterday, when Claire Danes revealed her left breast to the world.

The "Stardust" star was on MTV Canada to promote her new movie, when a loose-fitting shirt plus leaning forward equaled hello!

Welcome to the club, Claire! Meetings are held irregularly on TMZ, and Mischa usually brings the refreshments.
