Umbrella chords by Rihanna

I played around with chords and I liked how these chords sounded with this song, gives
a more soft sound. Maybe not the original key, but let me know what you think, with corrections etc.

VERSE 1

      C
You had my heart, and we'll never be world apart
      F
Maybe in magazines, but you'll still be my star
      C
Baby cause in the Dark, You can see shiny Cars
           G
And that's when you need me there
        F
With you I'll always share
  F
Because

CHORUS

 F
When the sun shines
        C
We’ll shine together
           G
Told you I'll be here forever
             Am
That I'll always be your friend
                     F
Took an oath Imma stick it out 'till the end
                C
Now that it's raining more than ever
               G
Know that we still have each other
             Am
You can stand under my Umbrella
             F
You can stand under my Umbrella
       C
(Ella ella eh eh eh)
      G
Under my umbrella
       Am
(ella ella eh eh eh)
       F
Under my umbrella
       C
(ella ella eh eh eh)
       G
Under my umbrella
        Am
(ella ella eh eh eh eh eh eh)
