Lyrics:

Mercedes: Excuse me, can I please talk to you for a minute?
Santana: Uh huh, sure you know, you look kinda familiar.
Mercedes: Yeah, you do too but, umm, I just wanted to know do you know somebody named...You, you know his name.
Santana: Oh, yeah definitely, I know his name.
Mercedes: I just wanted to let you know he's mine.
Santana: Huh... No no, he's mine.

Both:
You need to give it up
Had about enough
It's not hard to see
The boy is mine
I'm sorry that you
Seem to be confused
He belongs to me
The boy is mine

Mercedes:
I think it's time we got this straight
Let's sit and talk face to face
There is no way you could mistake
Him for your man are you insane

Santana:
You see, I know that you may be
Just be jealous of me
'Cause you're blind if you can't see
That his love is all in me

Mercedes:
Y'see I tried to hesitate
I didn't wanna say what he told me
He said without me he couldn't make
It through the day, ain't that a shame?

Santana:
Maybe you misunderstood
'Cause I can't see how he could
Wanna take his time, and that's all good
All my love is all it took

Both:
You need to give it up
Had about enough
It's not hard to see
The boy is mine
I'm sorry that you
Seem to be confused
He belongs to me
The boy is mine

Santana:
Must you do the things you do
You keep on acting like a fool
You need to know it's me, not you
And if you didn't know it girl, it's true

Mercedes:
I think that you should realize
Try to understand why
He is a part of my life
I know it's killing you inside

Santana:
You can say what you want to say
What we have, you can't take
From the truth you can't escape
I can tell the real from the fake

Mercedes:
When will you get the picture?
You're the past, I'm the future
Get away, it's my time to shine
And if you didn't know, the boy is mine

Both:
You need to give it up
Had about enough
It's not hard to see
The boy is mine
I'm sorry that you
Seem to be confused
He belongs to me
The boy is mine
You need to give it up
Had about enough
It's not hard to see
The boy is mine
I'm sorry that you
Seem to be confused
He belongs to me
The boy is mine

Santana:
You can't destroy this love I found
Your silly games, I won't allow
The boy is mine, without a doubt
You might as well throw in the towel

Mercedes:
What makes you think that he wants you
When I'm the one that brought him to
This special place that's in my heart
He was my love right from the start

Both:
You need to give it up
Had about enough
It's not hard to see
The boy is mine
I'm sorry that you
Seem to be confused
He belongs to me
The boy is mine
You need to give it up
Had about enough
It's not hard to see
The boy is mine
I'm sorry that you
Seem to be confused
He belongs to me
The boy is mine

Not yours
But mine
Not yours
But mine
Not yours
But mine

I'm sorry that you
Seem to be confused
He belongs to me
The boy is mine
