Simon Cowell revealed that he especially enjoyed working with “feisty” pop rocker Katy Perry.
The “American Idol” judge continued that “Waking Up in Vegas” singer wasn’t afraid to stand up to him during the judging process as he described her as feisty and quirky.
Simon, who is the headstrong and honest judge on the panel, added that he still won Perry over and the songstress did not know how right he was until she sat next to him.
