Lyrics:

[VVerse 1: Nicki]
Step-step-step up in the party like my name was bad bitch
All these haters mad because I'm so established
They know I'm a beast
Yeah, I'm a fuckin' savage
Haters you can kill yourself
In my space shuttle and I'm not coming down
I'm a stereo and she's just so monotone
Sometimes it's just me and all my bottles all alone
I ain't coming back this time

[Chorus: Nicki will.i.am]
I can't believe it
It's so amazin'
This club is heatin'
This party's blazin'
I can't believe it
This beat is bangin'
I can't believe it
(I can't believe it)
Hey, check it out
Check it out, check it out
Check it out, check it out
Check it out, check it out
Check it out, check it out
Check it out
Yeah, yeah, I'm feelin' it now
Check it out, check it out
Check it out

[Verse 2: will.i.am]
Step-step-step up in the party like my name was Mr. T
All these hating naggers ain't got nathing on me
Honestly, I gotta stay as fly as I can be
If you will get really, you get super OG
Honeys always rush me 'cause I'm fly-fly-fly
Dumb ones, they can't touch me 'cause I'm floating sky high
I stay nigger-rific you don't need to ask why
You just got to see with your eyes

[Chorus: Nicki will.i.am]
I can't believe it
It's so amazin'
This club is heatin'
This party's blazin'
I can't believe it
This beat is bangin'
I can't believe it
(I can't believe it)
Hey, check it out
Check it out, check it out
Check it out, check it out
Check it out, check it out
Check it out, check it out
Check it out
Yeah, yeah, I'm feelin' it now
Check it out, check it out
Check it out

[Bridge: will.i.am]
Check this motherfucker out
It got me in the club-in the club just rocking like this
Oh, oh, oh

Da done done
The sun done
Yep, the sun done
Came up, but we still up in dungeon
Da done done
Yep, in London
Competition, why yes I would love some
How the fuck they getting mad cause they run-done?
Mad 'cause I'm getting money in abundance?
Man, I can't even handle all these hundreds
Duffel bag every time I go to Suntrust
I leave the rest just to collect in-trust
I mean interest
Fuck my nemesis!
Exclamation, just for emphasis
And I don't sympathize, 'cause you a simple bitch
I just pop up on these hoes on some pimple shit
And put the iron to your face y'all wrinkled bitch

This is mega nigger
U-u-ultra niggmatic-matic-matic-matic
Ma-ma-matic

Oh, we just had to kill it
We on the radio, hotter than a skillet
We in the club making party people holler
Money in the bank means we getting top dollar
I'm a big baller, you a little smaller
Step up to my level you need to grow a little taller
I'm a shot caller
Get up off my collar
You a chihuahua
I'm a Rottweiler

[Chorus: Nicki will.i.am]
I can't believe it
This so amazin'
I can't believe it
This beat is bangin'
I can't believe it
This so amazin'
I can't believe it
(I can't believe it)
Hey, check it out
Check it out, check it out
Check it out, check it out
Check it out, check it out
Check it out, check it out
Check it out
Yeah, yeah, I'm feelin' it now
Check it out, check it out
Check it out
