The event also was a belated birthday celebration for the group as well, since immigration paperwork marks January 1 as their birthdays.
Sudanese native and current Chicago Bull forward Luol Deng hosted the party.
"This is great...we're from the same place. I get to do this every year .. See how the're doing...something that I love to do," said Deng.
The event was sponsored by the Chicago Association for the Lost Boys of Sudan, which provides mentoring, medical help, and other assistance to the group.
