a man invades the Red Carpet as the cast of " How to Train Your Dragon 2" poses

America Ferrera was the victim of a bizarre and invasive prank Friday at the Cannes Film Festival.

While posing with her How to Train Your Dragon 2 co-stars on the red carpet, Ukranian TV host Vitalii Sediuk dove headfirst underneath the skirt of Ferrera's gown. Security soon arrested Sediuk, but he didn't go easily, clinging to Ferrera's ankles until security finally pried him off.

Before security even arrived, Cate Blanchett was the first to rush to the actress' aid. According to The Hollywood Reporter, Blanchett immediately tried to push Sediuk away from Ferrera and asked whether she was okay.

"They were all so supportive. They all just wanted to know I was okay," Ferrera said.

As for the incident itself, Ferrera told the magazine, "It's fine — I'm over it."

This is not the first time Sediuk has crossed the line with celebrities. Heput his face in Bradley Cooper's crotch at the SAG Awards, crashed Adele's speech at the Grammys, and even received a well-earned smack in the face when he attempted to kiss Will Smith.

How would you have responded to such a "prank"?
