"At the moment I don't know when I'll marry. I had once said 2012, but for that too I have two years to go. Such things are not planned. You never know what's in store for you, but whenever it happens, I would love to wear something in green, " Katrina told repoters here.
"I don't know, why, but I have this thing in my mind, " added the 26-year-old, who is the Nakshatra brand ambassador.
Wearing a peach ruffled lehenga with jewel encrusted top by Neeta Lulla, the actress sported a chunky diamond set that was based on the traditional seven-stone floral cluster design of the brand.
