Tyson, who retired from professional boxing in 2006, shocked the world when he bit off the top of Holyfield's ear during a fight at the MGM Grand Garden in Las Vegas.
Despite the incident, both retired fighters embraced upon arrival for a promotional event for Holyfield's Real Deal barbeque sauce at grocery store Jewel-Osco in Chicago.
"I just wanted to see Evander, man," the Daily Mail quotes Tyson as saying. "I love Evander. I'm forever linked with him for the rest of my life."
Since retiring from boxing, Tyson has made cameo appearances in blockbuster films The Hangover and The Hangover 2.
