Veteran supermodel Christie Brinkley has stripped off to film an airline safety video in a bikini.

The 60 year old has joined a team of Sports Illustrated models to shoot a safety film with a difference for Air New Zealand.

In the film, Brinkley is seen giving out instructions while dressed in a skimpy swimsuit.

She is joined by models including John Legend's wife Chrissy Teigen and Jessica Gomes for the project, which the airline has dubbed "the world's most beautiful safety video".
