Aishwarya Rai Bachchan and Shah Rukh Khan may re-unite after 12 years for Rohit Shetty's next.

Buzz is the filmmaker has apparently casted these stars for the remake of 1958 hit film 'Chalti Ka Naam Gaadi’.

Earlier the leading lady's role was offered to Kajol, however, things didn't work out and blue eyed beauty landed the coveted project.

Rumour also had it that along with SRK, Rohit had signed Varun Dhawan and Arjun Kapoor. But Rohit put the rumours to rest, he said, "Arjun and Varun are my boys. I knew Arjun's mother, Monaji, personally. Also, I have high regard for David Dhawan, Varun's dad. I will definitely work with these boys and hopefully, they will agree to work with me (laughs), but I have not finalised them for my film with Shah Rukh. Once my final draft is ready, Shah Rukh and I will take a call on the remaining cast. Till then, everything you hear is mere speculation."
