Bollywood superstar Amir Khan Saturday said his next film "Delhi Belly", would have lot of abusive language and is a film for adults.

"Delhi Belly is a funny film and precisely a comedy. But one word of caution here. The film has an adult certification. It's not meant for children. We had applied for this certification mainly because of abusive language in the film," he said while talking to media persons at a programme on the Bengali version of "Kaun Banega Crorepati"

"I am saying this in front of you to inform the audience that here is a film which has abusive language. I respect sentiments of the people. There are certain people who may not be comfortable with the abusive language. It is not for children," he added.

Aamir, who has also done a item number in the film, said the song was a tribute to the disco era of Indian cinema during the 1980s.

"It is a tribute to the disco era of eighties led by Bappida (Bappi Lahiri), Mithunda who was known as disco king and Govinda," he said.

Aamir also sent out a warning at the item girls of Bollywood by saying that the era of item girls are over and now it's time for item boys to rock.

"And as far as the item dance done by me is concerned, it is a warning to Katrina Kaif, Deepika Padukone that the era of item girls are over now its time for item boys," chuckled the perfectionist of Bollywood.

When asked why he is taking so much time to release the film 'Delhi Belly', the 46-year-old actor confessed that he is not a multi- tasker.

"Earlier I was busy with 'Peepli Live', then I gave attention to 'Dhobi Ghat' and after that I took up 'Delhi Belly'. My problem in life is I am not able to do multi tasking. I am only able to do one thing at a time," said Aamir.
