A man is arrested by security as he tries to slip under the dress of actress America Ferrera (3rd R) in Cannes in this May 16, 2014 file photo.

I was covering the stars' red-carpet arrival for the film screening of "How to Train Your Dragon 2".

Suddenly Vitalii Sediuk, a Ukrainian journalist also known as a red-carpet prankster, tried to stick his head under actress America Ferrera's netted skirt.

No doubt feeling fabulous in her beautiful couture gown, the moment was clearly ruined for Ferrera.

I had only ten seconds to realise what was happening and take the shot. Security rapidly dealt with the culprit amid shocked looks from Ferrera and co-star Cate Blanchett. After a flash of appearing red faced and confused, the actress continued the red carpet walk as if nothing had happened.
