Shah Rukh Khan's kids Aryan and Suhana's stylish appearance at the airport made headlines and even their superstar father could not resist praising his "cool" children.

The 49-year-old "Happy New Year" actor took to Twitter to express his feelings about his all grown up children.

"Sorry but can't refrain from saying, I think they are turning out lean mean and very cool. I need to keep up," Shah Rukh tweeted.

Aryan, who will be turning 18 this November, was spotted wearing a black zipper with t-shirt and lowers. Apart, from his cool sense of dressing and modish hair style, what drove the online world crazy was his well defined jaw line and lean physique.

Suhana, 15, was seen doning a casual chic look with denim and boots.
