Brother and sister fight over pool boy in Coca-Cola's latest ad

Coca-Cola have added a gay twist to their latest ad — and it's going viral.

The commercial, called 'Pool Boy', begins with a teenage girl staring at the pool boy through the window, who's sweating as he fishes leaves out of the water in the sun. The camera then pans to a window upstairs where her brother is also checking him out.

The pair then go head to head for his affections by running to the fridge to grab him a cold bottle of Coke. Unfortunately for them, their mother has got there first.

The ad — which is part of their 'Taste the Feeling' campaign — has been praised for its honest portrayal of modern family life.

It's not the first time the company has highlighted diversity and equality in its commercials. Their 'America the Beautiful' celebrated citizens from all backgrounds speaking several languages.
