If celebrity power is good for one thing and one thing only, it's spreading the word, whether it's the news surrounding Prop 8, a school in need of funding and repair, or the latest, Kony 2012.

Since Monday, more than 56 million people (and counting) have viewed the 30-minute video unleashed by Jason Russell and Invisible Children, Inc.

Celebrities including Oprah Winfrey, Kim Kardashian and Diddy have also posted messages and links to the video on their Twitter accounts.

Celebrity photographer Tyler Shields took it one step further, writing STOP KONY with his own blood and posting a photo of the words on his website.

I painted this using my own blood lets stop the blood shed here! STOP KONY! Help spread the word! he wrote.

Meanwhile, Rihanna has reportedly reached out to Invisible Children about making her own video about raising awareness. According to TMZ, both sides are hoping to complete the new video as soon as possible.

Part of the Stop Kony 2012 campaign includes reaching out to The Culturemakers, 20 celebrity figures Russell and company categorize as When they speak, the world listens.

Click on any of their photos and the website generates a Tweet that reads: Help us end #LRA violence. Visit kony2012.com to find out why and how. @[celebrity Twitter handle] join us for #KONY2012.

Among the Culturemakers are Angelina Jolie, George Clooney, Jay-Z, Ben Affleck and Bono.

Lady Gaga, who is also on the list, will surely have a big impact on the campaign. If she posts anything on Twitter, all 20.4 million (a new Twitter record) of her followers will see it.

The Invisible Children's Kony 2012 campaign aims to stop Uganda warlord Joseph Kony and the Lord's Resistance Army from kidnapping children and turning them into soldiers and sex slaves.
