When the economic crisis hit the UK, many musicians are affected. But Bruno Mars had a benefit from these conditions.

Bruno Mars or Peter Gene Hernandez claims to be inspired to write ‘Billionaire’ when he exchange his U.S. dollars into pounds. When Bruno was on his way to London.

“When I was in London, I would like to exchange my dollars into pounds. So I gave U.S. $ 500 and I only get 200 pounds. I thought, ‘how could this happen?,” Bruno said as quoted by The Sun, Monday (20 / 2/2012).

That’s when the lyrics of ‘Billionaire’ began to set. Bruno began to hum a tune and trying to right his way.

“Travie came later, and put his touch, and the song entered the charts,” he added.
