Ranbir Kapoor and Deepika Padukone are all set to steam up the screen in their upcoming love story, the Sajid Nadiadwala-produced and Imtiaz Ali directed 'Tamasha'. Mirror has learnt that for the first time, the couple has a passionate love-making scene in the film which includes a lip-to-lip kiss.

According to a source close to the production, the film revolves around two young people who meet as strangers in Corsica and hit it off immediately. They are on a break from mundane everyday reality and playfully decide that their lives on the French island will be nothing but a pack of lies and go around impersonating the characters they have been fascinated with, from Dev Anand to Don and Mona Darling. "But somewhere along the way, they fall in love. The play-acting stops and feelings become real. The kiss between them is not very long in terms of screen time, but it's hot and intense and very different from the intimate kiss they shared in 'Bachna Ae Haseeno'," adds the source. The two actors were in a relation ship for two years, from 2008 to 2010, and after their break-up, surprised everyone by part nering in Ayan Mukerji's 'Yeh Jawaani Hai Deewani', three years later. Ranbir tried to play down their on-screen romance by pointing out that they approached their roles like two actors and because of the technicalities involved, the intimate scenes were no different from the action scenes. However, he did admit, that it was easier for them because they knew each other well.

Deepika in an interview reasoned that chemistry is intangible, you either have it or you don't. It cannot be created and Ranbir and she were fortunate that they had it.

The source insists that the chemistry between them sizzles in 'Tamasha'. Deepika had earlier pointed out (Mirror, June 1) that while she had worked with Imtiaz and Ranbir individually, in 'Love Aaj Kal', 'Bachna Ae Haseeno' and 'Yeh Jawaani Hai Deewani', it was a dream for her to make a movie with them together. When the opportu nity presented itself, both actors did what was required in the script professionally, without any 'tamasha'.
