I got a a bad bitch in my Chevy
Selling Miley Cyrus in my brand new Monte Carlo
I got that Justin Bieber please believe it

from Meek Mill (Ft. Rick Ross) – Believe It Lyrics on Rap Genius

Meaning

Please Belieb it!

Miley Cyrus is a “white girl” (cocaine) and Justin Bieber is “white boy” (heroin) — this is slang for drugs dating back to the 70s

He is also using word play with the word “believe” which is the name of Bieber’s last album

More recently, Ross has been hanging around with Bieber (though he’s one of the few rappers who Miley hasn’t been photographed with). Also note Diddy in the below picture.
