2 a.m., you're knocking
Telling me you want me
I say no, you won't go
Shut up, I don't want to know
What she does what she says
I don't wanna hear her name
When you're at my place
I'm sorry, it's her or me
I can't go on this way
I don't wanna be the other girl
The one who'll never be the only one in your world
Your mistress
Your mattress
Your selfish secret
I don't wanna be the other girl
The other girl
The other girl, no no
The other girl, no no
The other girl, no no
2 a.m., I'm with my friends
As you and her come walking in
You're dancing and kissing
And I'm just stuck here watching
Your lips on her neck
You're all over her and it's making me sick
I'm sorry, it's her or me
I can't go on this way
I don't wanna be the other girl
The one who'll never be the only one in your world
Your mistress
Your mattress
Your selfish secret
I don't wanna be the other girl
The other girl
The other girl, no no
The other girl, no no
The other girl, no no
I hate her, you need her
I know you'll never leave her
I'm not like her, I can't fight her
And I won't share, no no
Won't share, no no
No no no no no...
I don't wanna be the other girl
The one who'll never be the only one in your world
Your mistress
Your mattress
Your selfish secret
I don't wanna be the other girl
I just wanna be the only one in your world
Your Mrs
Your princess
Who knows all your secrets
I don't wanna be the other girl
The other girl
The other girl, no no
The other girl, no no
The other girl, no no
No no no no no...
