Actress Natalie Portman has learned not to book a chat show appearance on the same day as a doctor's appointment after struggling through an interview with David Letterman on America's The Late Show on Friday night (07Nov08).
The Star Wars star apologised to the host for appearing "woozy" on the show, explaining she had just come from the doctor's office.
She explained, "I got my blood taken... it's just for insurance for the thing (next film), so, if I faint just bring me an orange juice.
"They have to make sure you're not actually a junkie."
