Portman "woozy" on US chatshow

Natalie Portman admitted to feeling faint during a recent US chatshow appearance.

The actress told Late Show host David Letterman that her light-headed state was down to medical tests she had just undergone for a film role.

She said: "I'm a little woozy, I got a physical right before I came here. I got my blood taken. If I faint just bring me some orange juice."

She added: "Everything's fine, it's just insurance for a film I'm doing. They have to make sure you're not actually a junkie."
