Lyrics:

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?
What's he doin' in my world?
