She used to do tracks with Fabolous. She's also signed to Motown and Homeschool records so she's protected. Same situation French Montana had or Drake had with Cash Money where he was signed to Republic and Universal but also Cash Money as a partner.
In this situation, if Diddy tried to rip her off, Motown and Homeschool could sue him. Either way I wouldn't ever sign to Puffy. No one survives Puff.
