OVO OB
Wasn't he a rapper
They rap? Serious question
Would you call R Kelly an MC?Party does R&B rap. Ppl like to forget that kellz was rapping on 12 play. R&B rappers don’t get the respect they deserve.
And that’s why he got fukked up in his beefs. If he would have signed a pretty top tier rapper that was loyal to him.
