American Idol fans lined up for hours at the fest to chat with and get autographs from former contestants.
Before performing on the Spiedie Fest stage, Anthony Fedorov, Kevin "Chicken Little" Covais, and Nikko Smith met with some eager fans.
Out of thousands of contestants, all three made it to the final 10 on the talent show.
We caught up with contestant Nikko Smith, who loves giving back to fans who supported him on the show.
"While we were on the show it's like we were in a bubble, so we weren't really aware of the outside world. So it's good to give back the love that the people were giving us, voting for us and everything. So it's cool," Smith said.
American Idol contestant Constantine Maroulis also performed at Spiedie Fest this afternoon.
