A large and enthusiastic crowd of Hawkeye and T-Pain fans gathered in Hubbard Park Thursday night as part of the fourth annual Hawkapalooza celebration. The pep rally was just one of many festivities organized to celebrate this Saturday's Iowa-Iowa State football game.

Football players, cheerleaders, Hawkeye Marching Band members, turned out to rev up fans for what they hope is a winning weekend. The T-Pain show was free for students and the public.
