Though also spotted on BET’s Black Girls Rock! and the MTV EMA‘s respectively last night, music stars Mary J. Blige and Jason Derulo also lent their talents to the 3rd annual TeenNick Halo Awards.  The Nick Cannon-hosted affair sought to honor the humanitarian efforts of some of the nation’s most deserving teenagers.

Also featuring special messages from starlets Lady Gaga, Taylor Swift, and Serena Williams, the event’s featured performers – Blige and Derulo – brought the house down (with Blige pulling double duty).
