He told 'Entertainment Tonight': ''Cardi B man, she's doing her thing. God bless her.
''To get in the game, these are the rewards and the accomplishments that we all work hard for, [like] her Hot 100s.
''I remember getting my first Hot 100 No. 1. I know the feeling. I know how exciting that is. It's a drive to make you keep going more and more and more and more.
''Nothing but love for Cardi B and all the new artists out there doing their thing.''
