Bollywood star Aamir Khan is hosting a star-studded party Saturday night for Argentinian musician Gustavo Santaolalla, who is composing music for his wife Kiran Rao's directorial debut "Dhobi Ghat".

Gustavo, who has won two Oscar awards and 13 Grammy awards, has given music for movies like "Babel", "The Motorcycle Diaries", "Brokeback Mountain" and "The Insider".

He has been in Mumbai for a week. He came to get a feel of the city so that he is able to do justice to the music of "Dhobi Ghat", which has Mumbai as an important element.

Aamir, who also features in "Dhobhi Ghat" along with Prateik Babbar, is hosting an exclusive party for the musician at his Bandra house before the latter leaves Sunday, says a source close to the actor.

Aamir has extended a personal invitation to industry members like Shah Rukh Khan, Salman Khan, Karan Johar, Saif Ali Khan, Kareena Kapoor, Ranbir Kapoor, Katrina Kaif, Imtiaz Ali, Anurag Basu, Anurag Kashyap, his nephew Imran Khan, Rajkumar Hirani, Rakyesh Omprakash Mehra, Ronnie Screwvala-Zarine Mehta, Kunal Kohli, Shantanu Moitra, Swanand Kirkire and Shankar-Ehsaan-Loy.

However, Shah Rukh said he won't be able to attend the party as he was out of town for a vacation with his children.

Katrina and Kareena have asked him to host another party later because they won't be able to make it this time. While Kareena is travelling with her sister Karisma Kapoor, Katrina is busy shooting for Zoya Akhtar's next in Spain.
