What's he doin' in my world?
What's he doin' holdin' my world?
If he's not more than just a friend
Why were you kissin' him?
And what's he doin' in my world?

What's he doin' in my world?
Did you tell him that you're my girl?
If your love is really true
Tell him my world's made for two.
What's he doin' in my world?

Oh, don't let me keep on wonderin'
Just what you're gonna do.
Wondering if the one I love,
Loves somebody new.
What's he doin' in my world.

We don't need him here in our world.
So if it's true he's just a friend
Explain those kisses you gave him.
And what's he doin' in my world?...
