Shah Rukh Khan is considered the 'king of romance' in Bollywood, but unlike many who believe that romancing on screen is about chemistry, the superstar says it is all about comfort.

The 47-year-old, who has delivered hit romantic movies with actresses like Kajol, Rani Mukerji and Kareena Kapoor, says romance is more than just songs.

"Romance is not just about songs. Comfort is needed when you do romantic films. For me it's not about chemistry, it's about comfort. It's really difficult to look into a girl's eyes and say 'I love you' and then say the same thing to another girl," Shah Rukh said at a press conference here Sunday.

"When you get a chance to romance such beautiful girls, then work becomes easy," he added.

In his latest film "Jab Tak Hai Jaan", releasing Tuesday, Shah Rukh will be seen with two leading ladies - Katrina Kaif and Anushka Sharma. The movie, directed by late filmmaker Yash Chopra, is said to be a love triangle.
