Cowell, 56, says he refuses to puff cigarettes in front of little Eric, and now he's on a mission to get rid of his bad habit, reported Contactmusic.
"The idea is to cut down on the number. The Vape (electronic vapour cigarette) has been successful. It's a good one, it tastes nice and sweet. My driver was on 40-a-day and he has cut out smoking completely," Cowell said.
"I'm on 80-a-day now. It's a step in the right direction. I don't smoke in front of Eric for obvious reasons.
