A link to the news would be nice, but if true I will not be surprised, many of those superstars only do charity because, they reduce their taxes and just to look good on the eyes of the general public.
That's very true for most of them.
They even have their own foundations just to avoid the preying eyes of the Tax Collectors.
And with Beckham, I can say that maybe there's some truth with the leaked emails, though they were saying that those were faked. If those were tampered, the amount of money that the hackers want should not be that enormous & now it's like a terminating point for all his endorsements.
In the end, we don't know him in real person. So who are we to judge?
