On Oct. 26, Victoria Justice, Jason Derulo, Mary J. Blige and Kris Allen all showed up to support the honorees at Nickelodeon's 2011 TeenNick HALO Awards. The awards have been held annually since 2009 and were set up to honor kids and teenagers who strive to make the world a better and more peaceful place.

At the show, Victoria Justice wore a pinkish red cocktail dress and presented a HALO award to honoree Shanoah Washington, who has "contributed over 4500 hours of public service as a Jr. Leader, Teen Council Vice President and tutor for Project Learn" and "was also voted the 2010 and 2011 Youth of the Year."

Jason Derulo and Mary J. Blige both performed at the 2011 HALO Awards, which are set to air on Nov. 6 on Nickelodeon. We aren't sure which songs either recording artist performed, but from the looks of Jason's high-energy set, we're guessing it was either 'Don't Wanna Go Home' or 'It Girl.' Mary J. looks like she was performing a ballad -- maybe it was a new track off of her upcoming album 'My Life II... The Journey Continues (Act 1)'?

Taylor Swift and Lady Gaga are also supposed to be special celebrity guests at the TeenNick's 2011 HALO Awards, however, there aren't any pictures surfacing of the blond beauties yet. Tune in to the show to catch all of the action -- it airs on Nov. 6 at 8PM EST on Nickelodeon.
