Christina Ricci at 'Superheroes: Fashion and Fantasy' Costume Institute Gala at The Metropolitan Museum of Art. New York City, USA - 05.05.08

The actress was filming a scene with the animal for the cult cartoon-turned-action picture when the set started to vibrate.

And the chimp was so terrified it jumped onto Ricci - clinging to her chest in fright.

She says, "The whole set shakes, as it is supposed to for the scene, but the monkey freaks out and grabs my left breast.

"It was hanging off me, so I just leaned over, so its little feet could touch the ground and take some weight off my boob before the monkey ripped the whole thing off."
