Lyrics:

[Britney]
Till the world ends... Remix

[Nicki Minaj]
Hi
Chimpanzee's is hatin' but I take it all in stride
Put her in a jungle with bananas on the side
Told you they'd revive you, sorry but somebody lied
I ain't talking poultry when I say this chicken's fried
Anyway Britney, why they so jealous that you teamed up with me
Tell 'em they my son, yup, yella I'mma pick me
Anyway, burned , whats that, I don't know, femme fatale
Sniff, sniff, cries, I done slayed your whole entire f**kin' life
Oh oh, you got them ? out
I done balled all day you ain't touch the court
What, what you tired, you need a break
You was hot when? Ricki Lake!

[Britney]
With the cataclysm raining down
Inside's crying save me now
You were there impossibly alone

[Nicki]
It's Britney bitch
I'm Nicki Minaj and that's Ke$ha

[Ke$ha]
Do you feel cold and lost in desperation
You build up hope but failure's all you've known?
Remember all the sadness and frustration
Until the wor-or-or-orld ends waiting for

[Britney Spears - Verse 2]
And in a burst of light that blinded every angel
As if the sky had blown the heavens into stone
You felt the gravity of tempered grace
Falling into empty space
No one there to catch in their arms

[Ke$ha]
Do you feel cold and lost in desperation
You build up hope but failure's all you've known?
Remember all the sadness and frustration
Until the wor-or-or-orld ends waiting for

[Britney]
See the sunlight
We ain't stoppin'
Keep on dancing till the world ends
If you feel it let it happen
Keep on dancing till the world ends

[Ke$ha]
Keep on dancing till the world ends
Keep on dancing till the world ends

[Remix]
Woah oh oh oh oh oh woah oh oh oh

[Britney]
Woah oh oh oh oh oh oh woah oh oh oh oh oh oh
Woah oh oh oh oh oh oh woah oh oh oh oh oh oh
Woah oh oh oh oh oh oh woah oh oh oh oh oh oh
Woah oh oh oh oh oh oh woah oh oh oh oh oh oh

[Ke$ha]
Do you feel cold and lost in desperation
You build up hope but failure's all you've known?
Remember all the sadness and frustration
Until the wor-or-or-orld ends waiting for

[Britney]
See the sunlight
We ain't stoppin'
Keep on dancing till the world ends
If you feel it let it happen
Keep on dancing till the world ends
