Lady Gaga, Taylor Swift, David Beckham and Jessica Biel will help honor teenagers who are trying to help solve social problems in a Nickelodeon special.
The Teen Nick HALO Awards will air Nov. 6 with Nick Cannon as host. HALO stands for "helping and leading others."
Gaga is honoring Emily-Anne Rigal. She's a 17-year-old from Williamsburg, Va., who started the anti-bullying website and YouTube channel WeStopHate after she had to switch schools because she was bullied about her weight.
Gaga said Rigal has "strong convictions and a beautiful soul" and she took interest in her work because she feels passionate about anti-bullying efforts.
"I want families to take responsibility for raising their kids to honor one another," Gaga said.
James O'Dwyer, 19, of Tuscaloosa, Ala., started a disaster relief effort for people in his city and surroundings hit hard by tornadoes in April. Swift took notice of his work.
Shanoah Washington, 18, escaped an area of gang violence in California when her grandmother moved her to St. Petersburg, Fla. A spoken word artist, she started Sista2Sista, a mentoring program to motivate young girls, an issue that Biel has taken interest in.
Beckham, a Los Angeles Galaxy midfielder, is paired with Kyle Weiss, 18, of Danville, Calif. A soccer fan, Weiss and his brother started FundAField, an organization that raises money to build soccer fields in developing countries in Africa. Nine have been built so far.
