The Southern beauty started her career in Hindi film industry with Aamir Khan starrer blockbuster 'Ghajini' in 2008 and went on to work with Salman Khan in her second film 'London Dreams Last year.
When asked to pick out adjectives to describe the three Khans, Asin said, "Aamir is very focused, Salman has a cool attitude and Shah Rukh, from what I have seen of him, seems to be very charming."
The 24-year-old actress was in the capital recently to announce the 55th Filmfare Awards to be held on February 27 this year.
Asin has already bagged three filmfare awards - the first one in 2003 for being the Best Telugu Actress, second was the South Filmfare Best Actress Award for her performance in Tamil film, 'Ghajini' and the Filmfare Best Female Debut Award for the Hindi remake of the film.
"I hope to be nominated this year too, but my favourite film for this year's awards would be '3 Idiots'," said Asin, adding that the film was an "obvious choice" since it has been appreciated by all.
Even though she stepped into the film industry as a teenager, Asin, who hails from Kerala, never dreamt of becoming an actress in her childhood.
"It might sound like a cliche, but becoming an actress was never my ambition. I would have probably gone into academics like my parents. I am the black sheep in my family as no one else has any connection with films," said Asin.
Having said that, the Southern beauty, who has been a prominent face in Tamil and Telegu films for years now, does not regret her choice.
"Back then, I was too young to think about what I was doing, but now, I am happy with my profession," she said.
Asin has been often compared to another Southern beauty who has made it big in Bollywood, Sreedevi. When asked about the comparison, the actress said, "She is a great actress and is very close to me as we are neighbours. But I would like to make a name and place for myself in films."
The actress might be a newcomer in Bollywood, but is not jumping at every offer and taking it slow and steady in terms of film projects.
"I'm taking up select films which excite me, which is why I do not have a number of releases one after another. I have some films in hand now but none of them have gone on floors yet so I cannot reveal anything about them," said Asin.
She is also one star who belives in staying fit and positive but has no faith in the concept of size zero.
"Do I look like I could believe in size zero? To each his own, but I like to stay healthy and I think confidence, positivity and a good diet can achieve that," Asin said.
