Fergie was one of the many guest stars to take to the stage for ‘Dick Clark’s New Year’s Rockin Eve’ with Ryan Seacrest.

The singer donned a Christian Siriano Fall 2011 gown.

Most of the detail is lost on Fergie, but you can see from the runway that the green one shoulder fitted dress has a black sheer overlay and a ruffle detail cascading around the skirt.

She opted to sweep her blonde locks over one shoulder, with black shoes and flawless neutral makeup completing her look.
