With a Grace Kelly-esque updo, Mrs. O turned up her glamour quotient by accessorizing with three sparkly brooches (pinned to the frock's neckline), gold hoop earrings and a stack of gold bangles.
She was joined at the ceremony by Oprah Winfrey --we can't think of better representatives for the Windy City!
But despite Mrs. O and her golden glow, it wasn't meant to be for Chicago and the Olympics.
It was announced today that the 2016 games will be held in Rio de Janeiro or Madrid, but kicking Chicago out of the running "was one of the most shocking defeats ever handed down by the International Olympic Committee," reports Associated Press.
UPDATE 1:02pm: Rio de Janeiro is the official host of the 2016 Olympic games. Better practice that samba!
