Airline company Emirates has signed mega celeb Jennifer Aniston as the newest brand ambassador.

Rumours had circulated online about Aniston signing on with the brand for a cool $US5 million, according to The New York Post, with a spot already completed for the brand.

However, Emirates declined to comment on the cost or contract details.

“We can confirm that we are working with Ms Jennifer Aniston on a global digital and television campaign,” Boutros Boutros, Emirates’ divisional SVP for corporate communications, marketing and brand, told B&T via email.

“We do not wish to discuss contract details, and more information about the campaign will be unveiled in due course.”

The sign-on follows on from Emirates’ long-time competitor Etihad signing Nicole Kidman as brand ambassador in March.

Kidman appeared in a spot for the brand, created by M&C Saatchi.
