His fans look up to him as an idol, but superstar Shah Rukh Khan's daughter Suhana believes her father isn't the perfect youth icon as he smokes a lot.

"Daughter just reprimanded me... how can u be the youth role model if you smoke. So to all the youths out there... please don't smoke!!" tweeted Shah Rukh.

"Big reprimand for smoking from my strict little atom bomb of a daughter!!!" he added.

The 46-year-old is said to be a chain-smoker but has admitted smoking is the "worst habit".
