Madhavan was indeed very lucky to kiss a Brazilian model Maria Gomez in Teen Patti.
In Kites, they say the only best thing was the kiss between Hrithik & Barbara Mori.
Vidya Balan & Arshad Warsi's kissing scene in Ishqiya was perhaps the most intimate on-screen kiss.
Emraan Hashmi was on a break after his marriage, but he couldn't resist the temptation & so he kissed Shella Allen in Crook.
Neil & Deepika kissed in Lafangey Parindey after expressing their feelings for each other. Neil got cold feet before shooting as if it was his first time!
In the climax of Anjaana anjaani, Piggy Chops & Ranbir kissed...they are saying it was cute, but there wasn't anything remarkable about it. Actually I saw this one.
And yes I also saw this kiss & there was nothing about it except that they were in shower (so you can think about sex in the shower). I think there was another kiss which happened in front of Katrina. It might be an intimate moment for them, but it wasn't so for the audience.
Anushka & Ranveer also kissed in Band Baaja Baaraat but they say it was one bizarre kiss as it was done quite forcefully.
Anushka Sharma & Shahid were up to some badmaashi as they kissed in Badmaash Company.
Unfortunately I only saw the kissing scenes of Ranbir; the rest I do not know & I just don't believe what has been said. The best on-screen kiss can be the biggest joke of the century. Can't say as to who was the best kisser of 2010. It's difficult to give the award, but I'm sure they all must have looked better than Pooja Bhatt.
