The scene in question appeared in the 2012 Tamil/Telugu movie Maattrraan, which featured Suriya in a double role. Suriya and Suriya are at a cinema watching a film with Kajal's character, when Suriya #1 tricks Kajal into kissing Suriya #2.
None of this happened for real. As behind-the-scenes footage reveals, Kajal actually kissed a chroma cushion and Suriya kissed a plastic sheet.
Presumably it was preferable to kissing each other.
We'll let you watch the video for a bit more clarity. This must be what they call the magic of the movies.
Kajal Aggarwal, 31, is the star of films like Magadheera, Singham, Special 26, Maari and Brahmotsavam.
In Bollywood, she was last seen in Do Lafzon Ki Kahani with Randeep Hooda, whom she also kissed. We doubt that was for real too.
