Wu: I'm a dress maker, not a celebrity

Jason Wu, the man who created Michelle Obama's inaugural gowns, tells Anderson Cooper about his excitement and staying grounded.

"I always say, to do something like that, you have to sort of back it up with more hard work," says Wu about being chosen by the first lady and leveraging the opportunity.

The designer is thankful for the publicity, but prefers not to be in the spotlight. "I've always reminded myself who I am and what I'm here to do," says Wu. "I came to New York to be a fashion designer...at the end of the day, I'm a dress maker. I'm not a celebrity...it's very rare I do TV. I feel comfortable behind the scenes because that's where I have total control. I know exactly what I'm doing. I feel the most comfortable backstage at my shows."
