[Verse 1: Charlie Simpson]
You've always been this way since high school
Flirtatious and quite loud
I find your sense of humour spiteful
It shouldn't make you proud
And I know your pretty face gets far with guys
But your make up ain't enough to hide the lies

[Chorus]
Are you sure that you're mine?
Aren't you dating other guys?
Cause you're so cheap
And I'm not blind
You're not worthy of my time
Somebody saw you sleep around the town
And I've got proof because the word's going around

[Verse 2: James Bourne]
You left your phone so I invaded
I hated what I saw
You stupid lying bitch, who's David?
Some guy who lives next door?
So go live in the house of David if you like
But be sure he don't know Peter, John or Mike!

[Chorus]
Are you sure that you're mine?
Aren't you dating other guys?
Cause you're so cheap
And I'm not blind
You're not worthy of my time
Somebody saw you sleep around the town
And I've got proof because the word's going around
Don't know you
Ooh-ooh-ooh oh whoa-oh-oh

[Bridge: Matt Willis]
And I know that you try
To break me into pieces
And I know what you're like
But you can't hurt me now
I'm over you

Ooh-ooh-ooh oh whoa-oh-oh
Don't like you-ooh
Ooh-ooh-ooh oh woah-oh-oh

[Chorus]
Are you sure that you're mine?
Aren't you dating other guys?
Cause you're so cheap
And I'm not blind
You're not worthy of my time
Somebody saw you sleep around the town
And I've got proof because the word's going around

Don't like you
Ooh-ooh-ooh oh woah-oh-oh
Don't like you
Ooh-ooh-ooh oh woah-oh-oh
Don't know you
