Why am i so in love? (feat. chris brown)

Chris Brown:
You know what I'm thinkin'
You know that its you,
But some things need perfection,
Unlike you,

Chris Brown and Rihanna:
So why am I so in love?
Your the best thing in my life and always will be

Rihanna:
I'm so glad your mine,
You mean the world to me,

Chris Brown:
Your like a summers day,

Both:
I asked for your love,
you gave it to me,
I needed your trust,
the same as can be,

Rihanna:
I thought I would lose you,
but I knew i was wrong,

Chris brown:
So why did it have to happen,
when you sing this song,

Both:
I know my mistakes,
so light as a dove,
i learn from them all,
why am i so in love,

Rihanna:
'coz i need to know,
whats in my heart,

Chris Brown:
Like a love,
In my love chart,

Chorus
Both:
I asked for your love,
you gave it to me,
I needed your trust,
the same as can be,
Repeat chorus

Both:
My love is strong,
why am I so in love?
