PIX: INSIDE Mukesh Ambani's party for Bollywood

Mukesh Ambani's party for designer duo Abu Jani and Sandeep Khosla's book launch saw a record turnout from Bollywood.

While everybody from the Bachchans to the Roshans was present to lend their support, Saif Ali Khan's daughter Sara (extreme left) -- one of the people who feature in the book -- made her fashionable debut for the filmi set.

She led a bevy of models at the show, walking down the ramp -- and the spectacular Ambani stairway -- in the duo's creations.

Here's looking at what else happened inside the Ambanis' home, Antilla, where the party took place.

The star kid looked all grown up in an intricate multi-coloured lehenga as she walked down the stairs.

There were reports of her being flooded with movie offers when she made it to the cover of Hello magazine along with mum Amrita Singh a while ago. Quite a long way from this little girl.

All the star guests who modelled the designer clothes appeared on the stage.

Ambani matriarch Kokilaben (centre, in a peach sari) joined Amitabh, Jaya and Aishwarya Rai Bachchan, Sandeep Khosla, Sonali Bendre, Karan Johar, Tabu, Amrita Singh and Gauri Khan.

The Bachchans, one of the most loyal patrons of Anu Jani and Sandeep Khosla, were present to lend support to their favourite designers.

Abhishek Bachchan, however, could not make it as he is currently in Chicago, shooting for Dhoom 3.

The hosts and Amitabh Bachchan joined the designer duo on stage when it was time to launch the book titled India Fantastique.

Gauri Khan, who wore an embellished sari from the designers, posed for cameras with Shweta.

Meanwhile, hubby Shah Rukh Khan is busy wrapping up his Yash Chopra film in Leh.

Former supermodel and star wife Mehr Jesia went the ethnic route like everybody else while BFF Sussanne Roshan opted for a sparkly shot number.

Hostess Nita Ambani warmly greeted Waheeda Rehman, who also features in the book.
