Lyrics:

(Will.i.am)
Look out
Look out
Look out

Where it's at
I know karma's coming to pay me back (Pay me back)
I hurt the sweetest thang that's on the map
I broke her heart in 30 seconds flat
In 30 seconds flat

Now how did I, (How did I?)
Just how did I become that kind of guy (Kind of guy)
To look at girl and lie right in the eye? (Right in the eye)
My momma told me 'Willy, that ain't right.'
Boy now that ain't right

I'm s-s-s-sorry
I'm s-s-s-sorry
I didn't mean to break your heart
I didn't mean to break your heart

I'm s-s-s-sorry
I'm s-s-s-sorry
I didn't mean to break ya
B-b-b-b-break it baby

Look baby
I'm a heartbreaker
I'm a heartbreaker
I'm a heartbreaker
I'm a heartbreaker

(Cheryl Cole)
You're a heartbreaker
You're a heartbreaker
You're a heart

(Both)
I'm a heart
A h-h-h-h I'm a heart
A h-h-h I'm a

(Will.i.am)
Where she go? (Where she go?)
I got some things I gotta let her know (Let her know)
To fix the love now it's impossible (It's impossible)
But baby baby if we take it slow
If we take it slow

We can make it work (Make it work)
We just can't throw the love down in the dirt (Down in the dirt)
You probably think that I'm a fuckin' jerk
'Cause the way I let you down it made you hurt
I didn't mean to make you hurt

(Both)
I'm s-s-s-sorry
I'm s-s-s-sorry
I didn't mean to break your heart
I didn't mean to break your heart

I'm s-s-s-sorry
I'm s-s-s-sorry
I didn't mean to break ya
B-b-b-b-break it baby

Look baby
I'm a heartbreaker
You're a heartbreaker
I'm a heartbreaker
You're a heartbreaker
I'm a heartbreaker
You're a heartbreaker

You're a heart
A h-h-h-h I'm a heart
A h-h-h I'm a

(Will.i.am)
Break it down

(Cheryl Cole)
Let's break it down
Let's break it down
Let's break it down
Let's break it down

Let's break it down
Let's break it down
Let's break it down
Let's break it down

You're a heartbreaker
You're a heartbreaker
You're a heartbreaker
You're a heartbreaker

(Will.i.am)
I'm a heartbreaker
I'm a heartbreaker
I'm a heart
H-h-h-h-heart
H-h-h-h-heart
