It is a well known fact that both the super stars had issues in past with each other
Shahrukh and Akshay’s rivalry began when the latter made it very clear that he was unhappy with his role in Dil To Pagal Hai. The two then went on to make snide remarks at each other. Their rivalry deepened further when Shahrukh had a falling out with Salman Khan and Akshay became a good friend of the Dabangg actor. Farah Khan added fuel to the fire when after a fight with SRK, she cast Akshay in Tees Maar Khan. The situation worsened when Sanjay Leela Bhansali signed Akshay for his production Rowdy Rathore. Bhansali and Shahrukh haven’t been on the best of terms ever since their films Saawariya and Om Shanti Om clashed at the box office.
Also during their cold war--- Shahrukh had stalled the promotional event of Akshay’s Tees Maar Khan by distracting the public gathered for one of award show.

But we all know how media works these days and as per latest---both now are in good (not the best of )terms...
