Shah Rukh Khan and Deepika Padukone have been good friends ever since they both worked together in 'Om Shanti Om'. But recently, it seems like SRK must have hurt her feelings leaving her upset on the sets of their forthcoming film 'Chennai Express'.

Apparently, it is heard that on the sets of their film, SRK kept passing comments about Deepika's close bond with co-star Ranveer Singh with who she is simultaneously shooting for Sanjay Leela Bhansali's 'Ram Leela'.

SRK's behaviour didn't go down well with the actress as she is trying to keep her love life to herself after her much publicized relationship and break-up with actor Ranbir Kapoor. The team noticed the cold feeling between the two as they continued shooting.

Later SRK realized that Deepika was very upset, hence he apologized to her for passing those comments and sorted out their differences.
