"You're a... rockstar (baby)
Everybody wants you (everybody wants you)
Playa... Who can really blame you? (who can really blame you?)
We're the ones who made you"
This is basically saying "don't forget that you got really famous because of your comedy songs and celebrity bashing" or that Eminem would be nothing without the celebrities he's made fun of.
The chorus gives away what the song is about.
