KRK, who describes himself as an actor-producer, has often made several Bollywood celebrities the subject of insult filled-tweets. Last year, he was involved in a Twitter rant with Rishi Kapoor. Ranveer Singh allegedly blocked him on Twitter after KRK reviewed the actor's appearance on the controversial AIB Roast in the filthiest of terms. KRK's also been described by actress Sonakshi Sinha as a 'waste of space' and hashtagged a #lowlife by Queen's Lisa Haydon.
Sidharth, 31 and Alia, 22, made their film debut with Karan Johar's Student of The Year in 2012. The actors, who are rumoured to be in a relationship also co-star in Kapoor And Sons which opens in March this year.
