Rai wasn't comfortable doing such intense navel caressing &love making scene in the movie so the chemistry between the lead pair was lacking.
No skin show but at the end of the movie there we can Aishwarya'S Navel in red Saree , where dylan caress her navel,stomach and camera angles are close to her navel. This not considered as sex, it's just normal intimation.
During the start of the movie, Aishwarya is seen applying spices on her body including her waist and navel. Brief shots of the same is shown.
In an intimate scene towards the end of the movie Dylan is seen caressing Aishwarya Rai's navel and stomach and later passionately kissing her on her cheeks, chin and neck. Camera also takes a close-up of Aishwarya's navel. Rai's cleavage is visible. It is then symbolically shown that Dylan and Rai had sex thereafter. No nudity is seen although the top of Rai's breast can be partially seen very briefly
