Although the song is easy, it's more complex than the other tab proposes. Anyway here is 
correct version. Tabbed by Mathias Vinther

Verse:
Em          C        D        G
l've been thinking about you lately
Em     C        D        G
You're on my mind
Em   C           D        G
You do something to me baby
Em      C           D        G
In ways I can't define

Pre-Chorus:
C                D
Whatever you're doing
                Em
you're doing it well
              G
What is your secret
                  C
Won't you please tell

                 D
Cos my head is spinning
           Em
spinning around
                   G
You light me on fire

I won't let me down

Chorus:
Em          C        D
You put a spell on me
             G
I don't know what to do
Em        C
It's an ability
D              G
That draws me closer to you

C               D
Your magic has got me
        G        C
where I want to be
               D
Your magic is happening
  G
around me
