Salma Hayek knows how to make an appearance, even when she shows up at an emergency room.

The Frida actor was rushed to hospital after suffering a minor head injury while on a film set.

Unfortunately, she didn't have time to change out of costume before arriving but did have time to see the lighter side of the situation.

"My wardrobe for the scene was completely inappropriate for the hospital," she joked on Instagram in English and Spanish Friday, posing with the doctors who cared for her.

She was wearing a provocative nude-coloured tee shirt with breasts and hands that appeared to be grabbing at them.

Hayek, who has been in New York filming the comedy Drunk Parents with Alec Baldwin, assured fans she was fine following the accident.

"Don't worry," she told her followers. "It didn't make me any crazier than I was!"
