Apparently he hooks up with people while touring. But I would bet he makes people sign NDAs, not necessarily for malicious reasons, but to protect himself.
Sure but even beside that, just to illustrate the point: firstly, we have had a couple stories here from people who say they know girls who’ve hooked up with him. Secondly, it’s a big world of girls out there and a lot of buffer for gossip. Stories about gay celebs tend to get around more easily because the gay world is relarively small and if you live in NYC or LA you’re going to hear things. The world of heterosexuality is… vast.
