There's something inherently exciting about unintentional nudity. It's a fun, titillating spectacle to catch a celebrity's body part make its way into the frame of a film after they seem to have taken careful measure to avoid such an occurrence. What Culture (link below) pointed out a handful—like Jennifer Aniston's boobs showing up in a reformatted version of her Break-Up nude scene—but not being nudity experts, they also missed a few. Here are some of the best unintentional nude scenes in history...
Julia Roberts' breasts in Pretty Woman
Natalie Portman's right nipple in Closer
Amy Smart's lip slip in Crank 2: High Voltage
Femi Taylor's breasts in Return of the Jedi
Claudine Auger's lip slip in Thunderball
Kelly LeBrock's full frontal in The Woman in Red
Lindsay Lohan's left nip slip in I Know Who Killed Me
Charlize Theron's breasts in Aeon Flux
