[Chorus:]
She was a friend of mine
She left with my man
She lied, cheated, took all I had
She was a friend of mine
She used what she knew
She lied, cheated, and left me confused

[Verse 1:]
I feel so lost
Don't know why this has happened to me
My closest friend
I never could have thought it could be
You were someone
Someone I really thought I could trust
But my man, you laid and I'm betrayed

[Chorus]
She was a friend of mine
She left with my man
She lied, cheated, took all I had
She was a friend of mine
She used what she knew
She lied, cheated, and left me confused

[Verse 2:]
Thicker than blood
Wherever there was me there was you
My all was your all
But that wasn't enough for you
You had to see
And tried to walk a mile in my shoes
In my head, In my bed
Betrayed by my best friend

[Chorus]
She was a friend of mine
She left with my man
She lied, cheated, took all I had
She was a friend of mine
She used what she knew
She lied, cheated, and left me confused

I want to know why (why?)
You were my friend (why?)
I gave you all I had (why?)
Everything, everything that you want (why?)
You were my friend (why?)
Oh! My sister (why?)
Yeah, yeah, yeah, yeah (why?)

[Chorus]
She was a friend of mine
She left with my man
She lied, cheated, took all I had
She was a friend of mine
She used what she knew
She lied, cheated, and left me confused

[Ad-libs:]
You were, you were
How could you do this to me
You were my best friend
And everything you needed, I gave you everything
You left me alone
You lied, you cheated
Every little thing I had, yeah yeah yeah
You used all you knew
You liar, and you're a cheater
How could you do it?
How could you do it?
Yeah, yeah, you're a liar and you're a cheater
You were my friend, yeah yeah yeah
Oh, you're a liar
