JoJo, Soulja Boy, and Estelle Party at Miracle of Music Benefit

JoJo pulled off a leggy look in a blue body-hugging number while attending the Xbox Miracle of Music Benefit on the eve of the American Music Awards. The “Disaster” singer joined her peers including Soulja Boy and Estelle on the rooftop of Siren Studios in Hollywood to help raise money for Children’s Miracle Network Hospitals.

Video game fanatic Soulja Boy flaunted his wild style in a cheetah-print backpack while playing Kinect for Xbox 360, and Estelle kept it classy in a long patterned dress with leather jacket. The British songstress, who will co-host today’s online AMA pre-show, presented the 2011 Miracle Award to Eileen Garrido, an 11-year-old heart transplant recipient who started her own non-profit to help other young heart transplant recipients.
