Michelle Obama Wears Elegant Hairstyle for Barbara Walters Interview

After speculation over who would take the coveted top spot, First Lady Michelle Obama, pictured here in her official White House portrait, was revealed to be the award-winning journalist's Most Fascinating Person of 2009.

Obama wore her hair in a chic updo for the interview, a style that highlighted her cheekbones and complemented her high neckline. She kept her makeup simple, choosing light eye shadow, subtle liner and mascara. The First Lady decided to complete the look with some shiny pink lip gloss.

Walters asked Obama everything from her guilty pleasures to her workout regimen that keeps her famous arms so toned. Obama really lit up during the interview when talking about the First Family's newest addition, Portuguese water dog, Bo.

Above all else, the First Lady says she stays humble, admitting that she is still sometimes in disbelief when she pulls up to the White House and is greeted with a "welcome home."

Other people on Walters' list included Lady GaGa and former Republican vice presidential candidate Sarah Palin.
