(Verse 1)
Once upon a time, a few mistakes ago
I was in your sights, you got me alone
You found me, you found me
You found me-e-e-e-e
I guess you didn't care and I guess I liked that
And when I fell hard, you took a step back
Without me, without me
Without me-e-e-e-e
 [bad word] 
And he's long gone
When he's next to me
And I realize, the blame is on me
 [bad word] 
'Cause I knew you were trouble when you walked in
So shame on me now, flew me to places I'd never been
Til you put me down
Oh I knew you were trouble when you walked in
So shame on me now, flew me to places I'd never been
Now I'm lying on the cold hard ground

Oh, oh, trouble, trouble, trouble
Oh, oh, trouble, trouble, trouble

(Verse 2)
No apologies, he'll never see you cry
Pretends he doesn't know that he's the reason why
You're drowning, you're drowning
You're drowning-ing-ing-ing-ing
And I heard you moved on from whispers on the street
new notch in your belt is all I'll ever be
Now I see, Now I see
Now I see-e-e-e-e
 [bad word] 
He was long gone
When he met me
And I realize the joke is on me
Hey!
 [bad word] 
I knew you were trouble when you walked in
So shame on me now, flew me to places I'd never been
Til you put me down
Oh I knew you were trouble when you walked in
So shame on me now, flew me to places I'd never been
Now I'm lying on the cold hard ground

Oh, Oh, trouble, trouble, trouble
Oh, Oh, trouble, trouble, trouble

(Bridge)
And the saddest [bad word] creeping in...
That you never loved me... or her or anyone or anything
Yeah!

Some [bad word] from B!ebers' lyrics.
 [bad word] 
I knew you were trouble when you walked in
So shame on me now, flew me to places I'd never been
Til you put me down
Oh I knew you were trouble when you walked in
So shame on me now, flew me to places I'd never been
Now I'm lying on the cold hard ground

Oh, Oh, trouble, trouble, trouble
Oh, Oh, trouble, trouble, trouble

I knew you were trouble when you walked in
Trouble, trouble, trouble
I knew you were trouble when you walked in
Trouble, trouble, trouble!
