It was a tough competition. Both his children were vying for a gold medal in a Taekwondo competition and Bollywood star Shah Rukh Khan was a "nervous wreck" - till they won.

A sports enthusiast himself, both the superstar's children Aryan and Suhana are avid practitioners of the Korean martial art form.

"Yippee. Both the son and daughter won gold medals at Taekwondo championships. Suhana was all grit. Aryan all technique. I was a nervous wreck... love gold especially when the kids earn it, " Shah Rukh posted on his Twitter account Sunday.

Shah Rukh was conferred a honorary blackbelt in Taekwondo by the Korean Government in October last year.
