While Ranveer Singh and Arjun Kapoor may well dismiss rumours about a cold war which began way back in 2012, Mirror has learnt that a TV commercial that was to be filmed in the third week of June, was hit for a six because the actors refused to shoot together.

A source close to the development says, "Arjun was to fly down to Turkey and Ranveer who is on a cruise in Europe for Zoya Akhtar's Dil Dhadakne Do, was to join him there.

But the two actors didn't want to shoot together because the differences between them have multi plied since their last release.

During its filming, there were innumerable instances of one- upmanship as each tried to grab more footage and better lines.

So, now only Ranveer's portions will be canned in Turkey while Arjun will film his in Mumbai." In February this year, when the two were on the couch together for Karan Johar's chat show, they pretended to be the best of friends when on camera but barely spoke to each other once it was switched off.

Apparently, the problems began over Arjun's proximity to Ranveer's then lady love Anushka Sharma in 2012. When Ranveer got close to his Lootera co-star Sonakshi Sinha, Anushka started hanging out with Arjun and this did not go down well with Ranveer.

According to the source, "The negative vibes between the two have now become obvious and the script is now being reworked after which the actors will allot fresh dates to Lloyd, who will be directing the ad film."

When contacted, Lloyd hurriedly ended the call saying he was busy, then send a text message saying, "No comments."

Ranveer and Arjun remained unavailable for comment.
