And he has every reason to. Khan, one of the richest actors in the Hindi film industry, is still going strong as a hero, a quarter of a century after he emerged as a celluloid lover boy in 1992.
The 51-year-old actor, whose fans are all ready for his new venture, Imtiaz Ali's "Jab Harry Met Sejal", made his Bollywood debut with "Deewana", where he played the role of a young man called Raja in love with Divya Bharti's character of Kajal.
What is known so far about the film is that Sharma - Sejal - is a Gujarati tourist, who has lost a ring, and SRK, aka Harry, is a tourist guide.
What is also known is the word "intercourse" figures in it. Censor chief Pahlaj Nihalani wants the word to be snipped off, unless one lakh people write to him in support of it.
