Justin Bieber is always down to party for a good cause, and that's exactly what he did last night at the Pencils of Promise 2011 charity gala, held at Espace, in NYC! 

The Biebs, who arrived to the event looking quite dapper in a suit and tie, was honored by the organization for all of his generous efforts since the charity, which builds schools for children in need, began.
Other stars at the gala included Adrian GrenierMaria Menounos and Shaquille O'Neal
