Ok, I've actually had experience from places where paying for puss is normal.
1st, Beiber needs to make these hoes sign some paperwork of confidentiality and to keep their phones in a box outside the room or locked in a closet somewhere. Like you'll get that shyt back from my security after you leave...
2nd. Sometimes its just easier to pay for puss. Beiber is in a country where prostitution is normal. Is it right.. no, but everyone and their momma is probably a hoe. And if she isn't a prostitute but looks good, best believe she's expecting SOMETHING from the richest 19 year old on the planet. $500 is like 5 pennies to this lil nikka, I'm surprised she only asked for that much.
Beibs strikes me as the type of dude that gets whatever he wants most the time. So if he just wants to fukk, he's probably not gonna give a fukk about wining and dining a model chick and just pay her ass to catch his nut and leave. True, he does have millions of fans that will fukk him for free, but most don't look that good or already expecting shyt in return anyway or they think they puss is worth more than it is. She probably was like "I charge $500" and he was like whatever ho, get in the car
