Jessie J - Whos Laughing Now chords

Hey! This is my first tab... it sounds right to me but i sing
 it about an octave lower than usual! But if you're gonna 
sing it normally... try capo 1... if not, just keep putting the 
capo a fret higher then try it again and tell me what capo it is!!! :)

(Intro) Em             Em
[Beat  -----------------]  

Em                     Em
Mummy they call me names
They wouldn't let me play
I came home, sit and cry almost every day
"Hey Jessica, you look like an alien
Your green skin won't fit in this playpen"
Well they pull my hair
They took away my chair
I kept it in and pretend that I didn't care
"Hey Jessica you're so funny,
You've got teeth just like Bugs Bunny"

(Pre Chorus)
Am                             D
Oh so you think you know me now
                                Em
Have you forgotten how
                         Am
You would make me feel when you dragged my spirit down
                   D
But thank you for the pain
                               Em
It made me raise my game
But I'm still rising
I'm still rising
Yeah
    
(chorus)

 Am
So make a joke
Go provoke
  D
Blow your smoke
You're not alone
                              Em
But who's laughing now
Who's laughing now

Am
So raise the bar
Hit me hard
D
Play your cards
Be a star
                           Em
But who's laughing now
Who's laughing nooooooooow

[Beat] 

Em (for the whole verse)
Coz i'm in L.A
You think I've made my fame
FB makes us friends when you only really know my name
"Oh Jessie we knew you would make it
I got a track and I'd love you to take it"

Just because I'm signed
You think my pocket's lined
Four years now and I'm still waiting in the line
"Oh Jessie I saw you on YouTube
I tagged some old photos from when we was at school"

(Pre Chorus)

(Chorus)

(Bridge)
Em for the whole bridge
Jessie
She broke out of the box
Swallowed your pride, you got that ego cough (*cough cough*)
Let the haters hate
You're like, way too late
Click to see I got a message from you
"Hola, I'm proud of you"
"Oh my gosh, babe, your voice is like, wow!"
My reply, who's laughing now?

(Pre chorus)
