What was SRK doing on the sets of ‘Blue’?

Everyone on the sets of Shree Ashtavinayak Cine Vision Ltd.'s "Blue' was in for a pleasant surprise yesterday afternoon when none other than Shah Rukh Khan dropped on the sets to meet Akshay Kumar!
The team of "Blue' was shooting for a special number "Fikrana' and the BLUE theme song with Akshay Kumar and Zayed Khan.
While the crew was in the middle of the shoot, SRK walked on to the sets and greeted Akshay Kumar. The crowds went berserk seeing the two super stars together. The duo then stepped into Akki's vanity van where they spent nearly 15-20 minutes chatting with each other.
An eyewitness says, "We knew SRK was shooting nearby, but no one expected him to come on the sets of Blue. He surprised everyone including Akshay. They both even posed together for photographs!"
"While we were shooting for Blue on Floor 1 at Filmcity, SRK was shooting on Floor 12 for an automobile commercial. Though the distance is considerably large, Shahrukh Khan actually walked down all the way to meet Akshay. That was simply incredible!" says a source from the production team.
Looks like a new friendship is brewing in B-town!
