The Rohit Shetty-directed romantic-comedy brings back the iconic couple on screen after their 2010 outing "My Name Is Khan".
"Whenever, whatever we shoot, Rohit shows us what we have shot that day. There was a scene where I get hurt and AbRam felt it was because of Kajol. He was disturbed with it.
He looked at Kajol, saying 'papa tuth gaya'. I think for him our milan was not good," Shah Rukh said when asked what his children think of his and Kajol's pairing.
The duo along with the team of "Dilwale" spoke to the reporters here at the film's trailer launch.
Kajol's children Nysa and Yug accompanied her on the sets of "Dilwale".
Talking about two-year-old AbRam, Shah Rukh said he would not put pictures of his son AbRam on social networking sites.
"I am told not to tweet his pictures... He is getting more famous than me," he said in a lighter vein.
Kajol and Shah Rukh have made the audience fall in love with their sizzling on screen chemistry in films like "Dilwale Dulhania Le Jayenge", "Karan Arjun", "Kuch Kuch Hota Hai", "Kabhi Khushi Kabhi Gham" and "My Name Is Khan".
"We don't take ourselves seriously. We just have fun... We are good friends and all this shows on screen," Kajol told reporters.
Shah Rukh also said they are good friends and hence it works for them.
In Rohit Shetty and Shah Rukh's previous collaboration, "Chennai Express", the famous train sequence of "Dilwale Dulhania Le Jayenge" was re-created with him and actress Deepika Padukone.
When asked if there would be any other references from their SRK-Kajol's old films in "Dilwale", the 50-year-old actor said, "What bigger reference (you need) than Kajol and me in the film. We both feel honoured to be part of good films and working with good directors."
"Whenever I meet Rohit Shetty and Aditya Chopra, they both talk highly about each other. They respect each other's work. We had the train sequence in "Chennai Express" for fun element," he said.
Kajol, 41, said, "I find giving anecdotes boring. We have had great time working with each other."
