Los Angeles - Kanye West thinks he is "the worst celebrity".
The Stronger hit-maker - who is expecting his first child with girlfriend Kim Kardashian - launched into a bizarre rap-rant during his performance at the Adult Swim Upfront party in New York on Wednesday, in which he insisted he is too "real" to be thought of as a fame seeker.
He said: "One thing about me, I'm the worst kinda ... celebrity because all I do is make real music. All I do is sit in the studio and make real, real shit. And that's it.
"That's motherfucking it. That's motherfucking it. So I don't want nobody trying to run up on me with no cameras, trying to sell pictures and shit to magazines, asking me no dumbass questions, throwing me off of my focus and shit.
"Harassing you all motherfucking day. I ain't no motherfucking celebrity."
'Don't ask nothing else of me'
''I ain't running for office. I ain't kissing nobody's motherfucking babies. I drop your baby and you sue me and shit.
"I'm trying to make some music that inspires people to be the best they can be. I don't want nobody to ask nothing else of me. Don't ask nothing else of me.
"Motherfuckers chasing you down, 'bout to make you crash and shit and all they want is one nigger to laugh and shit."
Kanye - whose girlfriend tweeted from the audience to say he was "killin' it" on stage - will appear on topical comedy show Saturday Night Live this weekend but went on to insist he won't be appearing in any of the programme's famous sketches.
He added: "Hell nah, I ain't doing no motherfucking SNL skits; this my goddamn life. This ain't no motherfucking joke. That's it. Stop that shit right there."
