"It depends on how much I upset Simon in the live shows," he added. "There is no editing. If I am too naughty, maybe."
David joked that his constant mockery of Simon Cowell could see him lose his job
While the other Britain's Got Talent judges Amanda Holden and Alesha Dixon have remained silent on the issue of a new line-up, Simon previously hinted that change was in the air.
"I'm possibly looking at a shake-up for next year," he revealed. "It's about having a conversation to see how much they want to be on the show. Are they still into the idea of finding a star? I never want a judge for hire. I want someone committed."
Speaking specifically about David, the 54-year-old said "He goes too far at times. The more you say not to do something, the more he does it. He gets over-excited. He says and does things and sometimes regrets them, [but] I knew what I was getting when I hired him."
