This really has nothing to do with anything but it's so strange to find out Nelly is in the headlines at the moment because late last night, his song Number One randomly popped into my head and would not leave. And I haven't listened to Nelly in fucking years.
As far as those videos of him singing to young fans on stage, eh...he might be out of touch and though he was being sweet and making some young fan's dream come true or whatever. The hair twirling is a bit much, it's not like he's some tween star in a boy band or something closer to those girls' age so it comes off as behavior I wouldn't expect from an older rapper. Think he was high when he was up on stage? (And please, don't even think I'm excusing his hair twirling antics as "Oh, he was just high so it's okay." But obviously smoking weed or whatever the case may be does impair judgement cause you to do uncharacteristic things.) Sure, everyone on Twitter thinks it is disgusting but I'm fairly certain had it been some 40 year old female singer/rapper up on stage serenading a 10 year old boy, people would just go "Aw, that's sweet!". Double standards and such. It will always look creepier when it's an older male and a younger female, pretty much no matter what and that's a shame.
Regarding the rape, not much we can say now until more is released. No one was there except whoever was on that tour bus when it took place.
