Ex-girlfriends, don't talk about
You without me, don't talk about the past

In my head, it's only in my head
(Only in my head)
In my head, it's only in my head
(Only in my head)

There's just something about you
That gets me in a twist
And sometimes I think that cupid
Is just taking the piss

It only takes one word or idea
To send me in real deep
So if you think you're clever
Use the right words when you talk to me

Long distance, don't talk about
Ex-girlfriends, don't talk about
You without me, don't talk about the past

In my head, it's only in my head
(Only in my head)
In my head, it's only in my head
(Only in my head)

In my head, it's only in my head
(Only in my head)
In my head, it's only in my head
(Only in my head)

I, I, I, I really think I have a problem
I really can't control myself
Why do I get so suspicious?
Do you want someone else?

'Cause everybody wants everybody else
And everybody wants everybody else
Everybody wants everybody else
Oh everybody wants everybody else

Only in my head, it's only in my head

In my head, it's only in my head
(Only in my head)
In my head, it's only in my head
(Only in my head)

Long distance, don't talk about
Ex-girlfriends, don't talk about
You without me, don't talk about the past

Let's talk about the future
And lets talk about the wedding
Let's talk about Gwen Stefani
And lets talk about how much you like me and all that
