If the press back home is not chasing Aishwarya Rai Bachchan to get a glimpse of 11 month old Aaradhya, it's other obsession is speculating about the Bachchan bahu's weight. But the yummy mummy is oblivious to all this and continues to add feathers to her illustrious cap. The newly appointed Goodwill Ambassador for UNIAIDS, who has already appeared on chat shows hosted by David Letterman and Oprah Winfrey, will now be interviewed by British journalist Sir David Frost- best known for his interviews with former President Richard Nixon, which were later adapted on screen. Aishwarya has been chosen to represent Bollywood as a part of the new series called The Frost Interview which will feature persons who have brought a change and contributed to their industry through their own effort. The distinguished guests on the show will include former Beatle Sir Paul McCartney and Archbishop Desmond Tutu. The show will be a eight-part series of hour long interviews with the concerned people. Sir David Frost will visit Mumbai this week and interview Aishwarya even as the Bachchan parivaar gears up for Big B 's 70th birthday bash. We say it's time the critics look beyond Aishwarya's weight and eat humble pie as the actress has proven that when it comes to being an international ambassador of Bollywood, no one does it better than her.
