Nelly kind of turned mainstream R&B recently. My guess is that he was pandering to the audience. It doesn't really play that well for a lot of reasons.
Wasn't Freddie Gibbs also arrested and charged last year and did time and it turned out he never did a thing?
Like others here have said let's wait for facts and certainly not jump to any conclusions. Chances of this being a case similar to Gibbs are just as big as they are not.
Just saw the two videos. Since someone here mentioned Europeans. I'm Dutch and I would say it's a bit...... weird, unusual. I mean how young is that little girl? Yeah I can see why people are like "wtf" about that. So it's some kind of act he does during every show of his?
Also, isn't that girl a bit too young for a Nelly show?
I doubt that he's intending to go full creeper in front of a live audience.
