If I'm your boyfriend, you can have anything
(Anything?) anything, (anything?) everything
(Everything) I can upgrade you to better things (true)

from Justin Bieber (Ft. 2 Chainz, Asher Roth & Mac Miller) – Boyfriend (Remix) Lyrics on Rap Genius

Meaning

If you make Tity Boi yours, he’ll buy anything and everything you want because he’s rich like that.

While not likely, this could allude to the Jay Z track titled “Renegade” featuring Eminem.
