If you knew what you do
When no one's in the dark room
But me and you
A brilliant disguise
It's the taste of the chase
I do confess, it's the mess that feels so right

Come on a Monday, come on a Tuesday
They'll never know
Pop off a cork for Wednesday, play with me Thursday
But you'll always be his girl

Come on a Monday, come on a Tuesday
They'll never know
Pop off a cork for Wednesday, stay with me Thursday
But you'll always be his girl

His girl Friday, his girl Friday, his girl Friday
His girl Friday, his girl Friday, his girl Friday

Just a kiss, he won't miss
I know you're gonna miss this
As long as you live when you were mine
Bite your lip, pull me in, it's not the sin
It's the mess that feels so right

Come on a Monday, come on a Tuesday
They'll never know
Pop off a cork for Wednesday, play with me Thursday
But you'll always be his girl

Come on a Monday, come on a Tuesday
They'll never know
Pop off a cork for Wednesday, stay with me Thursday
But you'll always be his girl

His girl Friday, his girl Friday, his girl Friday
His girl Friday, his girl Friday, his girl Friday

If you knew what I knew
You'd thank god it's Friday
As I look on with you

Come on a Monday, come on a Tuesday
They'll never know
Pop off a cork for Wednesday, play with me Thursday
But you'll always be his girl

Come on a Monday, come on a Tuesday
They'll never know
Pop off a cork for Wednesday, stay with me Thursday
But you'll always be his girl

His girl Friday, his girl Friday, his girl Friday
His girl Friday, his girl Friday, his girl Friday
His girl Friday, his girl Friday, his girl Friday
His girl Friday, his girl Friday, his girl Friday
