America Ferrera ambushed as prankster climbs under her dress at Cannes Film Festival

America Ferrera became the latest victim to be ambushed when Ukrainian journalist, Vitalii Sediuk, laid on the ground and put his head under America Ferrera's voluminous white dress as she posed for pictures with her co-stars at the Cannes Film Festival.

Security quickly rushed out to the scene to remove the notorious pest while America attempted to remain calm. 

Meanwhile, her co-stars including Kit Harrington and Cate Blanchette were not impressed, and turned from the bank of photographers to look on in disgust at his actions. 

In the past, Sediuk has been slapped by Will Smith for trying to kiss him on a red carpet, crotch-hugged Bradley Cooper at a premiere and stormed the Grammys stage during Adele's acceptance speech. 

Looks like he has another prank to add to his book. 

Even the red carpet isn't safe anymore. Let's see who the next victim will be.
