According to TMZ, even though Russell is entitled to half of Katy Perry’s money in the divorce, he doesn’t want it!  (is he crazy? Or. just a nice guy at heart…?)

Russell Brand is entitled to approximately $20 million of Katy Perry‘s fortune … but TMZ has learned he will not take a single penny of it.

Russell’s lawyer filed final divorce papers Tuesday … although the judge will make the divorce official on June 30, because there’s a 6 month waiting period.

Informed sources tell TMZ … Russell and Katy did NOT have a prenup. As a result, everything they earned during their 14-month marriage is community property — which means they’re each entitled to 50% of the pot.

Katy made $44 million between May, 2010 and May, 2011 — according to Forbes. The couple married in October, 2010, so Russell could have scored a fortune if he exercised his community property rights.

But here’s the deal. As one source put it, “This divorce is as amicable as it gets, and Russell  doesn’t want Katy’s money. He’s happy to walk away with the money he earned — which is far less than what Katy raked in.

So the question is, Is Russell being naive? Or just an amazing guy?
