Priyadarshan Sengupta sends us this video link and a bit of cultural background from Wikipedia: Padma Lakshmi was brought up as a vegetarian and has admitted that because of this, she sometimes becomes "squeamish" when sampling other cultural delicacies. However, in 2009, she starred in a commercial for the Carl's Jr restaurant chain eating a Western Bacon Cheeseburger and credits the chain with bringing her away from vegetarianism.
Post Script: April 26: More insight via Amit Kathuria: The Naked Truth: "I tend to sleep in the nude. I'm an innately tactile person and a very sensual-leaning woman. You have to use the word 'leaning' or it sounds like I'm boasting! When I'm in my own private space, I do spend time with very little on."
