I Knew Had a Heart Attack (ft. Demi lovato)

I Knew Had a Heart Attack
Putting all my fences up
Cause I never wanna fall in love
If I ever did that, I think I'd have a heart attack
Once upon time
A few mistakes ago
I was in your sights
You got me alone
You found me
You found me
You bound me
(But when it comes to you I'm never good enough)

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
(to make it bounce like a basketball)
But you make me wanna act like a girl
Painting my nails and wear high heels
Yes you make me so nervous and I just can't hold your hand
You make me…
I knew you were trouble when you walked in
But I cover up, won't let it show
Flew me to places i'd never been
So I'm putting my defenses up
Cause I don't wanna fall in love
If I ever did that
Now i'm lying on the cold hard ground
trouble trouble trouble
I think I'd have a heart attack
trouble trouble trouble
I think I'd have a heart attack
Never put the steps for the other guys
When you come around, I get paralyzed
And everytime I try to be myself
It comes out wrong like a cry for help

It's just not fair
Seems more trouble than it all was worth
I gasp for air
It feels so good but you know it hurts
But you
He was long gone
When he met me (yes you)
And I realize the joke is on me
You make me…
I knew you were trouble when you walked in (ooh)
But I cover up, won't let it show
Flew me to places i'd never been
So I'm putting my defenses up
Cause I don't wanna fall in love
If I ever did that
Now i'm lying on the cold hard ground
trouble trouble trouble
I think I'd have a heart attack
trouble trouble trouble
I think I'd have a heart attack
(Aaah aaah) Love's feelings aren't lost in my arms
They're burning I'd rather be known
(Aaah aaah)And there's no one else to blame
(Aaah aaah)So scared I'll take off in a run
I'm flying too close to the sun
(Aaah aaah)And I burst into flames

You make me glow
When your sadest fear comes creeping in
That you never loved me or her or anyone or anything
So I'm putting my defenses up
Cause I don't wanna fall in love
If I ever did that, I think I'd have a heart attack (yeah)
I knew you were trouble when you walked in
So shame on me now (I think I'd have a heart attack)
Flew me to places i'd never been
So you put me down oh (I think I'd have a heart attack)
I knew you were trouble when you walked in
So shame on me now (I think I'd have a heart attack)
Flew me to places i'd never been
Now i'm lying on the cold hard ground (I think I'd have a heart attack)
Aaah Aaah trouble trouble trouble
I think I'd have a heart attack
Aaah Aaah trouble trouble trouble
I think I'd have a heart attack
I knew you were trouble when you walked in
Trouble, trouble, trouble (I think I'd have a heart attack)
I knew you were trouble when you walked in
Trouble, trouble, trouble!
