If I was your girlfriend
I'll be there for you, if somebody hurts you
Even if that somebody was me
Yeah-hee (break it down for 'em, B)
Sometimes I trip on how happy we could be

from Jay Z (Ft. Beyoncé) – '03 Bonnie & Clyde Lyrics on Rap Genius

Meaning

This section is an interpolation from the Prince song “If I Was Your Girlfriend”, and the borrowing was enough to get Prince a writing credit on the song

In the original, Prince is singing about the jealousy felt by the male narrator towards the closeness his girlfriend shares with her platonic female friends. An actual woman singing the song, as here, makes it far less interesting
