He is also a goodwill ambassador to Tanzania and founded charity organisation Care to Learn, which provides services for children living in poverty.

In the new commercial, he's described as the "second most famous Pitt" and offers viewers a Cribs-style glimpse at his simple lifestyle.

Doug is featured listening to music, playing basketball in his yard, building a birdhouse, mowing a lawn and cleaning his van.

The narrator of the advert says: "While his brother lives the life of a Hollywood A-lister, Doug's life is a little different.

"Virgin Mobile believe in a fair go for all and want to give Doug a taste of his brother's lifestyle, starting with his first ever celebrity endorsement."
