Mumbai, May 25 (IANS): Shah Rukh Khan is known for his professionalism and the superstar proved his commitment to work recently when he went to shoot for a toothpaste ad despite having fever.

Shah Rukh, the new brand ambassador of Pepsodent toothpaste, had to shoot for its latest ad campaign "Pappu and Pappa" at Filmcity for three days.

Even though Shah Rukh was down with 104 degree (Fahrenheit) fever, he made sure that it did not affect the shooting schedules. The actor made it a point to shoot for the campaign instead of cancelling it, said a source.

Shah Rukh has teamed up with child artist Keval and had to give multiple shots till his young co-star got it all right.

Shah Rukh did not complain throughout the long hours of shoot besides the numerous takes he was made to go through, said the source.

The ad is about a father-son relationship and on the sets Shah Rukh behaved a perfect dad encouraging Keval at every cut, pepping him if he would get bored.
