Yeezy was heavy on the scene yesterday, huh? From shopping with his homies Beyonce and Jay-Z, to joining Russell Simmons for #OccupyWallstreet, to then hitting not one but two parties in the city last night! His first stop was the afterparty for the Culo by Mazzucco book launch, where he rocked out with his protege Big Sean and fellow producer, Dr. Dre. Then he moved on to the premiere party of Read Between the Lines with actress Tracy Ellis Ross. Check out their pic below.
