Aishwarya Rai Bachchan seems to have brushed off the criticism that she was receiving when reports called her fat over her less than speedy baby weight loss. She recenty shut all of the negative chatter up when she flaunted her new slim frame in her latest appearance.

The Bollywood actress looked stunning as she displayed her slender post-baby body. Rai has finally shed the pounds since giving birth to her daughter Aradhya in November 2011.

The former Miss World attended the launch of a stem cell banking solution, LifeCell, in Mumbai on October 7th, according to International Business Times.

Rai wore a black Burberry suit that featured slacks and a blazer in which she looked very much back in shape as she let her long hair spill around her shoulders and down her back.

The 39-year-old was named the brand ambassador of LifeCell at the event, where she supported the cause of stem cell banking and even revealed that she too has banked her baby's umbilical cord stem cells.

She said, "Choosing to bank our baby's umbilical cord stem cells is a treasured gift that will stay with her for life and is an investment for her healthy future."

According to The Times of India, Aishwarya Rai also stated, "Aaradhya (her daughter with Bollywood actor Abhishek Bachchan) is a wonderful blessing in our lives and she is very special and it is a loving fulfilment. I am grateful for this experience."

She added, "I was aware about stem cell banking as a development probably out of my interest in the medical field as most of my friends are doctors. I have been aware of this way before I got married.

"I was always fascinated by it. Any research and development in general let alone in science and healthcare has always been of interest to me."

She explained, "The beauty of this association fulfils the wish of social encouragement. It is addressing a mindset that is fairly new to our country at large. I am happy to contribute, educate and make people aware about this scientific development."

However, when a reporter hinted at a second child she said, "I know what are you trying to ask. Whenever such a moment comes, you all will get to know. But please don't speculate till then."
