The concert will be available on TV on Palladia, the HD cable music channel owned by Viacom, or on Fuse.  If you’d rather watch the show on your computer, you can join the audience online at VEVO.com, AOL.com, Yahoo.com, VH1.com, NYTimes.com and at YouTube.

Organizers for the concert have recently revealed that a number of celebrities will serve as hosts for the event, including actresses Minka Kelly, Sophia Bush and Olivia Wilde, and pop singers Selena Gomez and Katharine McPhee.

The concert, which was created to raise money and awareness about global poverty, will air live on Saturday at 4 p.m. ET, and again at 12 and 8 a.m. ET the next day.
