Is Aishwarya pregnant or is it her good health?

Aishwarya Rai Bachchan was currently spotted at Roberto Cavalli’s 40th fashion anniversary party. As usual she rocked the party.

She was dressed in a silver fish-scaled flapper gown from Cavalli’s Resort 2009 collection.

Much to everyone’s surprise a conspicuous bump on her belly was noticed and this once again led to the rumor of her being pregnant.

What is the main reason behind this? It can either be her good health or it may be that her dress was too figure-hugging.

This party was also attended by bigwigs of the film industry including Abhishek Bachchan, Janet Jackson, Tyra Banks, Leona Lewis, Rachel Bilson, Heidi Klum, Naomi Cambell, Kylie Minogue, Taylor Swift and others.
