Sidharth Malhotra reacted strongly when Kamaal R Khan made a derogatory comment about his `Kapoor & Sons` co-star Alia Bhatt. He has asked the "Deshdrohi" actor to mind his own business.

Sidharth and Alia took to Twitter to post the cover photograph of a magazine, in which they are seen in swim wear. And to this Kamaal, who uses Twitter to express his personal opinion unabashedly, posted: `Alia looks so bacchi in panty but still some people keep forcing her to wear it.`

Sidharth, who is rumoured to be dating Alia, took offence to this, and tweeted: `Sir! We also try very hard to tell you to shut up but you keep tweeting! @kamaalrkhan`.

The retaliation led to a banter between the duo as KRK reverted by saying `Sir Ji @S1dharthM 130 crore people of India also try very hard to tell you to stop acting but you keep doing films to harass them.`

To this, Sidharth responded: `I think you need English reading classes sir, as you didn't read and understand my previous tweet!`


Kamaal summed up the verbal spat on the virtual medium by saying that he will take English classes from Sidharth.

When it comes to Sidharth and Alia, the duo have remained mum on the rumours over their relationship, but they have left behind hints suggesting their close rapport on many occasions. Now, Sidharth's lates comment will only add fuel to rumours of their bonding.

The two actors will next be seen together on screen in "Kapoor & Sons", produced by Karan Johar, along with Fawad Khan. Directed by Shakun Batra, the romantic drama is slated to hit theatres on March 18.
