Actress Kajol is all praises for her actor husband Ajay Devgn's upcoming film 'Singham'. "It is a rocking film. And one must see the film, " Kajol said, on the sidelines of a book launch here last evening. Tanisha, who was also present at the event, echoed what her elder sister said.

Directed by Rohit Shetty, 'Singham', an action film, stars Ajay and south actress Kajal Agarwal. It is a remake of the successful 2010 Tamil film of the same name. The Ajay Devgn starrer is all set to hit the cinema houses this Friday.

Even Ajay only has good words to say about the director of the film and is excited that the initial response to their new venture has been "roaring".

"Singham rocks, growls and ROARS! AAAAWESOME!!! Kudos to Rohit. His best so far... And so says Kajol, I think she really meant it, " Ajay had said yesterday on micro-blogging site Twitter.

Kajol, who was here to launch 'Champa, the Punjabi Kudi Discovers the Himalayas' and 'Champa The Dreamer Journeys to the land of Buddha', says, she likes reading fiction books.

"I read fiction books. I pick up children's book. I pick up teenage fiction books. They are very very hard to put up. I have read the Harry Potter books, which is a teenage fiction. But it is such an intelligent book and so well written, " Kajol said.

She further said that her husband is however not an avid reader. "He (Ajay) reads a lot of recommended books. If someone gives a book in his hand then he will read, otherwise not. I doubt if he has ever bought a book and read, " Kajol said.
