Nikki Blonsky: Three Cheers for Chéri!

Hairspray breakout star Nikki Blonsky keeps cool in a sheer LBD as she attends The Cinema Society’s screening of Chéri held at the Directors Guild of America Theater in New York City on Tuesday evening (June 16).

The Long Island-born actress came out to support her Hairspray costar Michelle Pfeiffer, who covers the July 2009 issue of InStyle.

Chéri revolves around the son of a courtesan in 1920′s Paris who retreats into a fantasy world after being forced to end his relationship with the older woman who educated him in the ways of love.
