Justin Bieber invests in charity Facebook game

Justin Bieber is investing his hard-earned cash into a new Facebook.com game which raises money for developing nations.

The Baby hitmaker signed on to back the new Sojo Studios social networking creation WeTopia this week (begs19Dec11).

As part of the virtual world game's objective, players must build up their land by buying and selling goods for points, which will then be transformed into real money for various aid projects.

Officials at Sojo Studios have also vowed to donate 50 per cent of its advertising profits to charity, splitting the funds between relief agency Save the Children, youth service organisation BuildOn and the Children's Health Fund.

Bieber says, "I've been so lucky and blessed and that's why I believe so much in giving back, and I know my fans will feel the same way when they play WeTopia."
