Everybody is aware of Shah Rukh Khan and Ajay Devgn's tiff during "Karan Arjun", which was two decades ago and it is believed that the duo has not been in good terms since. 

However, Kajol is the one common factor between the actors and recently, Ajay and SRK were spotted in Bulgaria having dinner together.

A picture of them, which has gone viral online, shows the duo discussing about something serious and fans hope that it is a new film project or a cameo scene by Ajay in "Dilwale"?

Both the actors have worked with Rohit Shetty and hence, he is also a common factor between the two.

SRK and Kajol are coming back together on silver screen after five years in "Dilwale" and the actors are shooting for the same in Bulgaria.

The film, which also features Varun Dhawan and Kriti Sanon, is slated to release on 18 December.

SRK will also appear in two other projects, "Raees" and "Fan", releasing next year.

On the other hand, Ajay is coming up with a big banner film this July -- "Drishyam". 

The thriller drama has been making waves, as it is a remake of Malayalam blockbuster, starring Mohanlal and Meena. The Hindi version, releasing on 31 July, has the "Singham" actor, Shriya Saran and Tabu in lead roles.
