At that time Rani was a newcomer and Aamir was already a star with hits like ‘˜Qayamat Se Qayamat Tak’, ‘˜Dil’ and ‘˜Jo Jeeta Wohi Sikander’ to his credit.After hit film ‘˜Ghulam’, Rani-Aamir came together on screen after seven years for the not-so-successful historical drama ‘˜Mangal Pandey’ and now they will be seen as a couple in forthcoming thriller ‘˜Talaash’, their third film in 14 years.Reminiscing her experience on the sets of ‘˜Ghulam’, Rani said: "When I did my first film with him, I used to look at his shoes as I used to be all tensed and nervous. I was a huge Aamir Khan fan. I had a crush on him. When I had seen QSQT (`Qayamat Se Qayamat Tak`), I was in school.""I was very nervous while doing a romantic scene with him. I would look at his shoes because I couldn`t look into his eyes because I feared I would fall in love with him," she said in a group interview."Now I look into his eyes. I keep gazing into his eyes until he asks me not to," added the actress who did a special appearance in Aamir-starrer "Mann".The two enjoy a good friendship off the screen and Rani hopes it is for lifetime."Over the years, Aamir and I have built a friendship which, I would like to believe, is for life. I would like to believe that I will be attending his 80th birthday also," she said.Rani, 34, is all praises for Aamir, 47."He was a superstar when I did my first film with him and he is a much bigger superstar even now. His focus, dedication and sincerity towards his craft, his approach towards filmmaking, performance and character, has become greater and bigger with time," she said.
