Aishwarya Rai Bachchan has declined to endorse the celebrity doll Barbie on her 50th anniversary due to paucity of time.Ever since Aishwarya won the Miss World title in 1994, there have been numerous attempts to immortalise her as a Barbie Doll. However, due to her professional commitments she had to postpone the endeavour of the company Mattel.

"Mattel again proposed that Aishwarya Rai Bachchan endorse the Barbie doll but as her prior commitments stretched her for time she had to decline yet again. The turn of the millennium special edition celebrity doll was to feature Naomi Campbel among others," a statement issued by Aishwarya's spokesperson said here today.

On the eve of the favorite doll's 50th anniversary, Aishwarya is still the most sought-after celebrity to be passed off as a celebrity Barbie.

Mattel was also keen to have Aishwarya walk the ramp on Lakme Fashion Week as 'Barbie dolled up' in a design as Single Likeness Barbie, which would be unveiled and auctioned for a charity of her choice.

Conversely, due to her pri or commitments which includes filming of Vipul Shah's "Action Re play" and her being honoured with Padmashree, she opted out of the event as she did not want to inconvenience the producer/director anymore while taking time out to this event, the spokesperson said.

"Nonetheless, the earlier ideas have been revised, all the possibilities and talks of a business venture with Aishwarya & Barb i.e. is still in the process of being finalized. So, whether Ash-Barbie doll will hit the shelves or not is something only time will tell," the spokesperson added.
