Rocker Beck credits controversial faith system Scientology with fuelling his blossoming career and helping him achieve elusive happiness.

The contentious religion is often eyed with suspicion, but the GUERO singer insists the Scientologist way of life, which is also shared by celebrity followers such as Tom Cruise, Katie Holmes and John Travolta, brings great happiness.

He says, "Scientology brings a certain happiness and fullness to things.

"It has reinforced certain things that were really constructive and good.

"If you actually look at what's been done through Scientology and what's come out of it, I think it blows away the criticism."
