Okay, so maybe you're tired of seeing them all over reality TV, but the Kardashian sisters are now using the spotlight for a cause - gay marriage. Kim, Khloe, and Kourtney Kardashian are the latest celebs to join the NOH8 campaign, which fights to overturn Proposition 8. Prop 8 was an amendment to the California State Constitute that banned same-sex marriage. What’s with the duct tape you ask? It symbolizes their voices not being heard – a feeling shared by tons of Californians, gay or straight, famous or not. The list of stars who’ve posed for the campaign is endless – Ashlee Simpson, Pete Wentz, Steve-O, Isaiah Washington, and Kathy Griffin are just a few of the big names.

What do you think of this campaign? Is it enough for celebs to just pose for photos, or should they be doing more for their cause? Sound off in the comments, and be sure to check out the NOH8 website to find out more and to see all the photos. Then, consider starting a gay-straight alliance if your school doesn't have one.
