Jordin Sparks & Greyson Chance Perform at the MDA Telethon!

Jordin Sparks and Greyson Chance lent their beautiful voices to an awesome cause over the weekend.

The two performed on the MDA Telethon which raises money for the Muscular Dystrophy Association.

Greyson performed "Unfriend You" while Jordin performed "The Cure." Other celebrities who participated included Lady Antebellum, Billy Ray Cyrus and Jennifer Lopez. 

The telethon raised $61.5 million for MDA which combats neuromuscular diseases through programs of worldwide research, medical and support services.  It also provides children affected by the disease with an opportunity to go to a cool summer camp!

We think it's an awesome organization and loved seeing some of our faves perform.  In case you missed it, check out their performances below!
