The actress, who is married to Anurag Kashyap, kisses debutant actress Keerti Kulhar in the scene, which revolves around a game of 'spin the bottle', Hindustan Times reports.
Director Bejoy Nambiar said: "It was quite funny and spontaneous when we shot for the scene since Keerti was completely unaware of the fact that we were shooting a kiss.
"What you see in the scene is the real deal. Her expression is completely off-guard and natural."
Shaitan is about bored city-dwelling teenagers entertaining themselves through a series of high-risk escapades.
The actress will next be seen in the road movie Zindagi Na Milegi Dobara, which also stars Hrithik Roshan and Katrina Kaif.
