Kanye West Brings Out 2 Chainz at Samsung Galaxy Launch Party (Video)

To celebrate the launch of the new Samsung Galaxy Note II, Kanye West performed and brought out special guest 2 Chainz at Manhattan’s Skylight for the New York City crowd Wednesday night. The artists did a surprise performance of 2 Chainz’s single, “Birthday Song.” Good*Fella Media was there to capture the moment.

BONUS: Kanye also dropped a “freestyle about NYC” mixed with a little “about seeing someone you haven’t seen in a while and you want to see right now” over the “Say You Will” instrumental. Footage after the jump. [via Miss Info]
