While his recent hot chemistry with Parineeti Chopra in ‘Shuddh Desi Roamace' made rounds it is also rumoured that the actor will be locking his lips with Anushka Sharma in Rajkumar Hirani's Peekay. But Sushant's flirting and romancing onscreen with his co-stars seems to give insecurity to his girl friend Ankita Lokhande such that their relationship is getting dicey.As per a daily tabloid, Sushant who was shooting for Yash Raj's next was interrupted by his ladylove. A miffed Ankita approached on the sets to meet him.Once Sushant met her, Ankita asked him to give his cell phone. The actor without any hesitation handed over his set to her.Tabloid further states that after checking out his set, Ankita had a tiff with Sushant. The argument went so worse that Ankita slapped him. However, when asked about it, both denied it amusingly.Earlier, when Sushant was asked about what his girlfriend has to say about his kissing clause in the flicks, the actor replied that she is very casual about it as she knows it's all professional.But from the above incident it appears that Sushant's closeness to the actresses is giving complex to Ankita, which is quite obvious.The couple who is in a relationship for past four years is also reported to marry each other by the year end or next year.We hope everything goes well between them. Watch couple's candid moments.
