Minaj revealed on her Twitter account that after speaking with Kanye West, it took her about a week to write her verse. She recorded her verse in-studio with West and Rick Ross in Hawaii.
In 2013, West admitted that he briefly considered removing Minaj's verse from the track because he knew it was the best; at the time, he was worried that after working on his album for eight months, people would still say the best part was someone else's. He ultimately decided not to remove her because he said it would have only been because of his own ego and would have denied her the platform she needed to "be all she could be."
"Monster" was sent to radio on September 21, and it was released to the iTunes Store on October 23, 2010 around Halloween. It spent five weeks on the Billboard Hot 100, peaking at number 18 on the chart. The song also appeared within the top 30 on both the Billboard Hot Rap Songs and Hot R&B/Hip-Hop Songs charts. The song also appeared on the UK Singles Chart at position 146. "Monster" was certified platinum on March 31, 2014.
In the "Monster" music video, directed by Jake Nava, Nicki is seen halfway through owning the roles of both her popular alter egos, Barbie and Roman Zolanski, with Blac Chyna standing in as her double. In her scene, it appears that Roman has tied Barbie up and has taken her hostage. While rapping her verse as Roman, she seduces Barbie whose head is covered by a bag. Then Nicki exchanges roles and raps as Barbie, and she continues switching between both alter egos throughout the whole verse. Both alter egos are rapping about how the other is not as rich or good as them. Unfortunately the music video has been banned on many websites and televsion networks, but it can still be viewed on some websites.
"Monster" Nicki Minaj Verse Lyrics
Pull up in the monster automobile, gangsta
With a bad bitch that came from Sri Lanka
Yeah I'm in that Tonka, color of Willy Wonka
You could be the king but watch the queen conquer
OK first things first I'll eat your brains
Then I'm a start rocking gold teeth and fangs
Cause that's what a motherfucking monster do
Hair dresser from Milan that's the monster do
Monster Giuseppe heel, that's the monster shoe Young Money is the roster and a monster crew
And I'm all up, all up, all up in the bank with the funny face
And if I'm fake, I ain't notice cause my money ain't
So let me get this straight, wait, I'm the rookie?
But my features and my shows ten times your pay?
Fifty K for a verse, no album out!
Yeah, my money's so tall that my Barbiez got to climb it
Hotter than a Middle Eastern climate, find it
Tony Matterhorn, dutty wine it, wine it Nicki on them titties when I sign it
That's how these niggas so one track minded
But really really I don't give a F-U-C-K
Forget Barbie, fuck Nicki cause she's fake
She's on a diet but my pockets eating cheesecake
And I'll say bride of Chucky is child's play
Just killed another career, it's a mild day
Besides Ye, they can't stand besides me
I think me, you and Am should ménage Friday
Pink wig, thick ass, give them whiplash
I think big, get cash, make them blink fast
Now look at what you just saw
This is what you live for
I'm a motherfucking monster
