It's the season of giving, and why not have some fun with your festivities!

Virgin Mobile has teamed up with What's Trending for a live holiday fundraising spectacular! YouTube stars, celebrities, and bands wuill perform live from both New York and Los Angeles. One of our favorite comediennes -- Heather McDonald -- will be doing standup.

It's all for a great cause. For every viewer that tweets the hashtag, #Tubeathon, during Dec. 13, Virgin Mobile will donate $1 to Covenant House, a non-profit organization with shelters around the country serving homeless youth. The Covenant House has shelters in 22 cities throughout the United States, Canada and Latin America, including homes in New Jersey and New York that were recently decimated by Hurricane Sandy.

So check out this digital variety show above and be sure to tweet #tubeathon!
