[Intro]
Oh, yeah
Yeah, yeah

[Verse 1]
Phone rings at a quarter to nine
Some crazy girl is on the line
Talkin' bout how I better recognize
Found my phone number in his Calvin Klein's
And I'm like, what's that gotta do with me?
Your man is the one who needs questioning
'Cause there ain't nothing that you're gonna achieve
By calling me and giving me the third degree

[Pre-Chorus]
And if he's your man then tell me
Why was he sweatin' me
All up in the club last night
Telling me I'm the type of girl he likes
If you say you don't believe (Don't believe)
He was acting that way
Girl, I wish you could've seen
How your man was checking me

[Chorus]
Girlfriend, let me give you something
I know that you love him
But you should've saw him last night
You ain't his girlfriend anymore than I am
I know you see him
But, girl, you really should've saw him last night
[Verse 2]
Oh, no, no, you didn't say
That I need to back away
I thought you heard when I told you that
It ain't my fault if he wants me back, no
All that's been said to me, it don't really mean a thing
You need to realize that I'm not the one
You should call with an attitude

[Pre-Chorus]
And if he's your man then tell me
Why was he freakin' with me (Messin' with me)
All up on the floor last night
Saying things I know you wouldn't like
But you say you don't believe (You can't believe)
He was acting that way
Girl, I wish you could've seen
How your man was checking me

[Chorus]
Oh-oh
Girlfriend, let me give you something (Oh)
I know that you love him
But you should've saw him last night (Oh, yeah, last night, girl)
You ain't his girlfriend anymore than I am (Anymore)
I know you see him
But, girl, you really should've saw him last night
[Bridge]
Oh-oh
Did you really think your man was down for you?
Did you really, really think that his love was true?
If you had been loving your man right
He wouldn't have been puttin' it on me all night
You weren't his girl last night (Girlfriend, girlfriend)
Baby

[Chorus]
Girlfriend, let me give you something
I know that you love him (Yeah)
But you should've saw him last night
You ain't his girlfriend anymore than I am
I know you see him
But, girl, you really should've saw him last night

[Post-Chorus]
Girl, you really should've saw him

[Refrain]
Girlfriend, I know that you love him
But-but you should've saw him last
Saw him last night-night-night
Anymore than, girlfriend-friend
Know you see him, girlfriend
Saw him (I saw him)
Saw him last, saw him last night-night
Girlfriend
[Chorus]
Girlfriend, let me give you something
I know that you love him
But you should've saw him last night
You ain't his girlfriend anymore than I am
I know you see him
But, girl, you really should've saw him last night
