Ya'll gotta use Ockhams Razor...
Char probably smashed along with the homies, grabbed some liquor for her as well. Shorty was wit it, then regretted it. Got the police involved, didn't want to go through with it because of the embarrassment. This story plays out with teenagers and young adults everyday.
I'm not downplaying it, or saying Charlamagne isn't wrong. The x-factor to me is, did he know she was underage beforehand.
The snippet of Star interview I heard, shorty didn't sound like a victim, she sounded like she wants a check.
