'The Bachelor' host Chris Harrison was the co-host of 'Live With Kelly' on Friday, and Kelly Ripa asked him a question that all 'Bachelor' fans are interested to know: Which Bachelors did he not get along with during filming over the last 21 seasons? Although Harrison first hesitantly responded, "You know how much this will stir things up? This will just ruin my life for the next month!," he eventually spilled the beans, admitting that it was Charlie O'Connell.
