The wrestlers and some of their celebrity friends were in South Los Angeles Friday on a mission to combat bullying among kids.
They wanted to send the message that bullying is not acceptable whether physical or electronic.
Some stars present included singer Jordin Sparks, "Dancing With The Stars" processional dancer Chelsie Hightower and actor David Arquette.
The stars and athletes shared with a group of school children about their own experiences with bullying, and what they should and shouldn't do if they are bullied in school.
The event was part of the Be A STAR campaign - STAR stands for "show tolerance and respect."
Wrestling star Rey Mysterio reminded the children that what he does for a living is just for entertainment that goes on in the wrestling ring.
"It doesn't matter what age. Put your foot down. If you don't bully, make sure that if you do see somebody bullying, you go ahead and make your way through and have that person stop," Mysterio said.
Rep. Linda Sanchez of Cerritos said she has introduced legislation at the federal level to stop the growing phenomenon of bullying.
"It's not harmless. Certain generations just think that bullying has always happened. It's kind of a rite of passage, that kids grow out of it, it's a phase, it's character building. But the fact is, bullying is really harmful," said Sanchez.
