Bollywood megastar Shah Rukh Khan has unveiled a new statue of him in London's Leicester Square, saying it was like having a "life-size doll".

"I think I'm looking very handsome. You're also looking very pretty," he told his co-star Kajol, who is also depicted in the statue.

"It's like a second thought, but thanks," she responded, with a laugh.

The statue marks 30 years of the longest-running film in Indian cinema, Dilwale Dulhania Le Jayenge, starring both actors.

Khan, a household name in India, is one of the country's most popular stars with millions of fans domestically and abroad.
