Katrina Kaif is garnering a lot of praise for gyrating to item number "Chikni Chameli" in Karan Johar's forthcoming film "Agneepath", but the actress says the "lavni" style dancing was not a cakewalk for her.

"The response to 'Chikni Chameli' has been fun so far. It was hard work. It was very fast and it was not a style I was used to, but I took it as a challenge...

I think we all went for it as a team and did the best we could. I am happy people are liking it," the 27-year-old actress said here while launching new range of Panasonic airconditioners.

Even actor Salman Khan is smitten by the song and Katrina is happy about this.

"He has not told that to me but I think that's a great thing. He has a great taste in music and songs. So, if he likes it then it's great," said Katrina who featured in two more item numbers in "Shiela ki jawani" and "Bodyguard".

New Year is round the corner and Katrina is pleased with the way 2011 shaped up for her.

"2011 has been a really great year for me. All the goals I had in hand, I think everything turned out really well.

I am very grateful for that...The best I could have wanted to come out of every project has come true this year," said Katrina who had two releases this year - "Zindagi Na Milegi Dobara" and "Mere Brother Ki Dulhan".

Industry members are also smitten with the song. They feel it will definitely be a USP of Karan Johar's remake of his father's classic "Agneepath", and overshadow "Munni", "Sheila", "Shalu" and "Jalebi bai" item numbers.

Composed by national award-winning duo Ajay-Atul, the spicy song, sung by Shreya Ghoshal, is the Hindi version of their own Marathi hit "Kombadi palali".

The lyrics of the number, penned by Amitabh Bhattacharya, are as cheesy as they could get, but the rhythm is extremely peppy and catchy. And Katrina's vigourous moves and sensual expressions, choreographed by Ganesh Acharya, go in total sync.

The 26-year-old had set a benchmark with "Sheila ki jawaani" last year, but with this song, she has surpassed it with her killer desi look.

"Agneepath" director Karan Malhotra is all smiles and believes Katrina has done full justice to the song.

"I think the way the song was made, it was so wonderful, that only a topmost actress could have done justice to the song.

And as far as Katrina is concerned, her USP is that she has never been seen in any film in that kind of zone that 'Chikni chameli' is in...which is why she also stands out in that atmosphere and that is why the song is catching a lot of eyeballs, " Malhotra said at the music premiere of "Agneepath".

As much as he avoids talking in media about Katrina, even Salman Khan, her former beau, couldn't stop raving about the song.

"I love the song! I saw it a few days back and I am completely smitten by it. A lot of hard work has gone behind it and it is visible on the screen. Hats off to Katrina. She has come a long way, " Salman said at a recent event in Mumbai.

A 30-second promo of the song was first launched, followed by an over two minutes-long video on YouTube. The video has registered over 3 million hits so far, and producer Karan Johar is ecstatic.

"The nation is singing and dancing to 'Chikni chameli', so I am really excited about it. It is already an established big hit song, " Johar said.

According to Atul Gogavale, "Katrina spent eight days in rehearsal before starting to shoot the song. It took nine days to finish the shoot, and her energy levels never saw a dip."

"This song has a very high tempo and requires speed in steps. Even if I or someone else wants to dance to it, you cannot match up to the tempo for more than two minutes. But Katrina just took it to another level. She has left us speechless, " he said.

Celebrities from the film fraternity feel Katrina has raised the bar of item numbers with her energetic dance steps.

Writer Milap Zaveri tweeted: "Katrina's dance steps in 'Chikni Chameli' are too brilliant and energetic! But there should be a disclaimer saying 'Don't try this at home!'"

"'Chikni chameli' from 'Agneepath' is just outstanding. I have never seen an actress dance like Katrina does - she raises the bar to another level, " tweeted Ritesh Deshmukh, who recommended Ajay-Atul as composers for the film.

Even choreographer Vaibhavi Merchant, who has choreographed item numbers like "Kajra re" says she is in awe of Katrina's effort.

"Katrina is looking very good in 'Chikni Chameli' and I told Karan (Johar) about it. I really loved it and whenever Katrina comes and does a song like this, you know what the effect is, " she said.

The action-drama slated for a Jan 26, 2012 release, features Hrithik Roshan as Vijay Dinanath Chauhan, originally played by megastar Amitabh Bachchan in Chandan Barot's directorial venture of the same name.

Priyanka Chopra, Sanjay Dutt and Rishi Kapoor will also be seen in key roles in the movie.
