Shah Rukh Khan's HAPPINESS mantra...

Bollywood superstar Shah Rukh Khan, who is currently busy shooting for director Imtiaz Ali's next "The Ring", says work always makes him happy.

"Work always makes me happy, but when it's with beautiful people like Vaibhavi (Merchant) and team... Imtiaz and his mad boys and girls, it's like the happiest," Shah Rukh tweeted.

"The Ring" also stars actress Anushka Sharma. This will be the third time that the actress will be sharing screen space with Shah Rukh, with whom she earlier worked with in "Rab Ne Bana Di Jodi" and "Jab Tak Hai Jaan".
