Hollywood loves a good cause. From dolphins to disasters of the natural kind, celebrities are, more often than not, quick to latch on to a crisis.
The latest one is particularly tragic. In September at least five teenage boys committed suicide after being tormented for being gay -- most recently Rutgers University freshman Tyler Clementi. Now, actors, musicians, comedians and celebrity personalities are making moves to stop teen bullying.
Kathy Griffin is donating all proceeds of her Dec. 16 comedy show at Los Angeles' Gibson Universal Amphitheatre to The Trevor Project, an organization focused on suicide prevention among LGBT youth. Advice columnist Dan Savage created the "It Gets Better" Project, in which people can upload videos to YouTube offering support and hope to LGBT teenagers. Gossip blogger Perez Hilton joined Savage's effort and is urging celebrities to jump on the bandwagon as well.
"I lost about 200,000 followers on Twitter because I was tweeting these celebrities to ask them to make videos," Hilton told ABCNews.com. "I don't regret it. I'd do it again. I'm happy I lost 200,000 followers on Twitter because I was able to get a lot of celebrities to make videos."
Among them: Tim Gunn, Sarah Silverman, Ashley Tisdale, Jewel and Eve. The list keeps growing. Hilton said he talked with "Glee" creator Ryan Murphy about having the cast of the Fox hit show make a video and working an anti-bullying theme into "Glee's" storyline.
Having once been a closeted gay teen in an all-boys high school, Hilton said he's wholeheartedly committed to this cause.
"What's really powerful is to admit and acknowledge that we've all been bullies," he said. "I've been a bully, I can still be a bully on my website. The point is to not be a bully to the point where someone is going to want to kill themselves -- threatening violence, calling them homophobic names repeatedly. I'm not asking anyone to be perfect. I'm not perfect. I just want people to engage in this conversation."
Droves of stars are speaking out about their own experiences being bullied and what teens and adults can do about bullying. Take a look at nine more of the anti-bullying movement's loudest celebrity advocates:
"I think that the way that we had trickle-down economics in the '80s, this is trickle-down homophobia. And I really want people to connect the dots. And that's why I believe there's a connection between Prop 8, 'don't ask, don't tell,' and now the string of teen suicides. It's almost sanctioned to bully gay people and treat them as second-class citizens. And I get very nervous when the parents of these so-called bullies defend them, saying, 'Oh, kids will be kids,' when you find out that the teen suicide rate is four times higher for a gay person."
"I've been bullied. And you know what hurts? The collusion. I remember one time I was getting my butt kicked in a park when I was a little kid. And I'll never forget a guy walking by with a briefcase, just walking by. And I feel like at this time we can't be that guy anymore. We can't walk by anymore." -- "Larry King Live," Oct. 4.
