You know that I'm a crazy bitch

I do what I want when I feel like it

All I wanna do is lose control

Oh oh

But you don't really give a shit

You go with it, go with it, go with it

'Cause you're fucking crazy rock 'n roll



You said 'Hey, what's your name'

It took one look and now I'm not the same

Yeah, you said 'Hey', and since that day

You stole my heart and you're the one to blame



And that's why I smile

It's been a while, 

since every day and everything has felt this right

And now, you turn it all around, 

and suddenly you're all I need, the reason why 

I smile



Last night I blacked out I think

What did you, what did you put in my drink

I remember making out and then oh oh

I woke up with a new tattoo

Your name was on me and my name was on you

I would do it all over again



You said 'Hey, what's your name'

It took one look and now I'm not the same

Yeah, you said 'Hey', and since that day

You stole my heart and you're the one to blame



And that's why I smile

It's been a while,

since every day and everything has felt this right

And now, you turn it all around,

and suddenly, you're all I need, the reason why 

I smile



You know that I'm a crazy bitch

I do what I want when I feel like it

All I wanna do is lose control (x2)



And that's why I smile

It's been a while,

since every day and everything has felt this right

And now, you turn it all around,

and suddenly, you're all I need, the reason why 

I smile



The reason why, I smile

The reason why, I smile
