And that’s because a man rushed on to the red carpet at the Cannes Film Festival and crawled beneath her dress.
Security officials quickly pulled the man away as he pushed his head under America’s voluminous gown before the premiere of How To Train Your Dragon 2.
It was a bizarre incident on a red carpet renowned for its strict decorum.
The man was later identified as Vitalii Sediuk, a Ukrainian prankster known for such stunts.
America looked concerned – and who wouldn’t? – but didn’t let the fool spoil her red carpet outing and was in good spirits at the movie’s after-party, laughing with guests and taking pictures, although she declined to comment on the incident.
