Used to be so pure
Like a diamond fresh out the store
Innocent teacher's pet
It's so crazy how quickly you forget
I was the one, baby, who let your hair down
I taught you every little trick you're using on me now
Said you got nerve, lady, get your revenge out
We know you'll be coming back around
So why you acting so conceited?
Gave me no attention like I'm out of season
(I'll frustrate ya) she's so conceited, it's like I don't exist
But she really don't mean it, she really don't mean it
She used to be my girl, she used to be my girlfriend
She took everything but left her heart on my door step
You used to be my girl, I used to be your boyfriend
She'll be running back again, ay, ay, ay
Wow (wow), to her aura (her aura)
Like a siren so loud, can't ignore her
It's amazing, her transformation
Trying to knock me right out her equation, yeah
I was the one (the one), baby, who let your hair down (let your hair down)
I taught you every little trick you're using on me now
Said you got nerve, lady, get your revenge out
We know you'll be coming back around
So why you acting so conceited?
Gave me no attention like I'm out of season
(I'll frustrate ya) she's so conceited, it's like I don't exist
But she really don't mean it, she really don't mean it
She used to be my girl (be my girl), she used to be my girlfriend
She took everything but left her heart on my door step
You used to be my girl, I used to be your boyfriend
She'll be running back again, ay, ay, ay
If you are tryna get back with baby
Every call up your radio station
Dedicate this one here to your lady, to your lady
If you're missing your baby
(She used to be my girl, she used to be my girlfriend) oh, yeah
(You used to be my girl, I used to be your boyfriend)
