It has been barely few hours since Kapil Sharma introduced his lady love Ginni to the world through social media and now the ace comedian is once again making news, but for all the wrong reasons.A source close to The Kapil Sharma Show informed us, that recently while returning from Melbourne and Sydney after performing a stage show Kapil hit co-star Sunil Grover on an Air India flight.The incident took place when Sunil was seated on his seat and Kapil suddenly walked up to him and started hurling abuses.In no time he held Sunil by his collar and raised his hand on Sunil. The actor, who plays Dr. Mashoor Gulati on the hit show didn't respond to Kapil's abuses and beating and stayed mum.The Kis Kis Ko Pyaar Karoon actor was allegedly drunk and called Sunil names like Tu Mera Naukar hai, tere show flop tha...". The entire team soon came to Sunil's rescue and took Kapil away. The airlines has not taken any action against Kapil till now.Kapil and Sunil have both unfollowed each other on Twitter.This is not the first time that both of them are making news for their rivalry. For the uninitiated Sunil had quit their previous show Comedy Nights with Kapil as he wanted hike in pay package and Kapil had refused it. The former then went on to host a show on Star Plus named Mad In India.We tried contacting Kapil and Sunil, but both remained unavailable for comments.
