Slumdog Millionaire star Dev Patel stopped in to chat with Jon Stewart on The Daily Show last night, and both of them were cute as buttons. Dev was obviously thrilled to be on the show, even exclaiming, “I’m 18 and I’m on this show. I shouldn’t be doing this!” After that Jon pretended to grumpy because Dev is 18 years old and still has, in Jon’s words, “that new car smell.”

Dev Patel is also joining the cast of Indian-American director M. Night Shyamalan’s The Last Airbender. The Last Airbender is based on a children’s television show. UPI has more:

Dev has a kind of relentless enthusiasm, and you can just tell he’s having the time of his life as he attends all of these big Hollywood functions. He seems like a really sweet kid – I hope he stays that way.
