Bollywood star Katrina Kaif has donned a rockstar look in her upcoming film Mere Brother Ki Dulhan, releasing September 9.
Katrina will be seen in the song I Am A Rockstar, that will introduce her in the film co-starring Imran Khan and Pakistani pop star-turned-actor Ali Zafar, says a media report.
While the song is yet to go on air, the first look of Katrina's new avatar has impressed all those who have got a sneak peek.
In the song, Katrina is seen making a number of casual chic fashion statements, ranging from ripped orange jeans and hot denim shorts to sleeveless tops and off- shoulder tees.
She will be strumming the trademark guitar of course, to complete the rock style, along with kohl- lined eyes to add a grunge effect.Katrina's look has been styled by Rocky S. and Aki Narula. 
Since Ranbir's bandana-laden rockstar look has already been leaked online, Bollywood fans can't wait for the upcoming battle of Bollywood rockers.Of course, Katrina isn't essaying a rockstar in her film.
“ The song is an introduction to Katrina's happy- go- lucky character in the film. She plays a maverick who lives by her own rules, and that's what the image being portrayed in the number,” said a source.Incidentally, this is the second time in as many films that Katrina will be donning a Bohemian character.
In her last release, Zindagi Na Milegi Dobara , she impressed all playing a half US-half Indian character who lives life to the fullest on her own terms.
Co- incidently, as part of the promotions of Zindagi Na Milegi Dobara , Katrina participated in a rock concert in the Capital along with her co- stars Hrithik Roshan, Farhan Akhtar, Abhay Deol and Kalki Koechlin.
The show dampened the plans of Rockstar , since director Imtiaz Ali was planning a similar live rock concert featuring Ranbir to promote his film.Mere Brother ki Dulhan is written and directed by debutant filmmaker Ali Abbas Zafar. The film marks the return of Ali Zafar, who created waves with his histrionic skills in last year's Tere Bin Laden.
