Naveen presented an award to Maggie Grace at the Breakthrough of the Year Awards (given by Hollywood Life Magazine) on 4 December 2005. Here's a quick interview they had after the show:
Naveen with Maggie Grace on the Lost set (Season 1).
Naveen has always had a great admiration for Maggie and her talent. He was very sad when she left the show partway through Season 2 of Lost. They have remained very good friends, though!
