Celebs Join Live Dance Marathon for a Good Cause (VIDEO)

Who's Up for O's?
See the nominees for the 2011 MTV O Awards.
With the MTV O Music Awards set to give props to the web’s most interactive and beloved music stars of today on Monday night, there’s a lead-up event that’s also bringing a bit of starpower online — and it’s all for charity.

Starting at 12:30am EST, MTV will be livestreaming their attempt to break the Guinness World Record for the longest dance group marathon. Celebrities like Dancing With the Stars pro Peta Meragatroyd and America’s Best Dance Crew group We R Heroes will be just a few of the influencers dropping by, and it’s all to raise money for various LGBT organizations and promote tolerance.

Why start at midnight? The goal is to break the existing record during Monday night’s O Awards, which will be streamed online starting at 11:30pm EST.
