Penelope lets out a pop as cola brand gets fizzy

HOLLYWOOD star Penelope Cruz lets out an embarrassing burp in a new advert for Coca-Cola aimed at helping the drink regain its fizz with consumers.

Tom Cruise, the actress’s boyfriend, helped direct the commercial, which is part of a multi-million dollar campaign to portray Coke as “natural and relevant”.

Ms Cruz, 28, is shown guzzling down a bottle of the soft drink in front of a dinner packed with men before accidentally belching.

She is one of several stars to appear in adverts for the promotion called Coca-Cola ... Real.

Friends actress Courtney Cox is shown outwitting her husband, David Arquette, by getting the most of the last Coke in their fridge by filling his glass up with ice.

And boxing legend Muhammad Ali, who rarely does adverts, promotes the drink by shadow-boxing with inner-city children in Miami. The promotion was launched after executives decided the previous Life Tastes Good campaign had gone flat.
