Estee Lauder's fragrance launch for "Modern Muse" at the Guggenheim Museum on Thursday, Sept. 12, attracted many celebrities, but one in particular stood out for revealing a bit more than she likely anticipated.

Maggie Gyllenhaal, who went braless in a see-though, floor-length, long-sleeved dress, bared a bit more than expected. The 35-year-old actress and husband Peter Sarsgaard seemed blissfully unaware of her wardrobe malfunction as they posed happily for photographers.

Gyllenhaal recently starred in "White House Down" alongside Channing Tatum and Jamie Foxx, and she just wrapped filming on the upcoming drama "Frank" with Michael Fassbender.
