Paris Hilton appeared to have run out of fake tan while bronzing her unusually large feet before her appearance on Letterman on Monday.

The heiress was radiating her usual orange glow as she posed for pictures outside the Ed Sullivan theatre in New York – except for her size 11 flappers which were still a pasty shade of white.

Paris has been earning her 'single busiest person on the planet' tag this week.

As well as modelling her new sunglasses line on The Late Show, she has been shooting an ad for her hair accessories range AND attending the MTV Movie Awards.
