《What If》是Colbie Caillat演唱的歌曲，詞曲由Colbie Caillat創作，收錄於專輯《Between Two Evils》中。
歌詞如下：
What if we fall in love
What if we both die young
And what if we get married
With ten kids and a song
And what if we run away
To some tropical island
And what if I get to keep my car
With the third row and the automatic?
What if, what if, what if we
What if, what if, what if we
We build a house from old books and driftwood
And I'll paint our bodies blue
And what if he loves me more than life itself
And tells me I'm his only true friend?
What if, what if, what if we
Oh, what if?
I don't know what you're made of
But I hope it's fire and hope and dreams
And what if I fall in love with you again?
And we're both wearing pearls at our temples?
Oh, what if? Oh, what if?
Oh, what if? Oh, what if?
(Chorus)
What if we fall in love? What if? Oh, what if?
(Bridge)
Oh, I don't know what you're made of
But I hope it's fire and hope and dreams (Oh)
And I hope you love me more than life itself (Oh)
And I hope you're not just like the rest of them (Oh)
Oh, what if? Oh, what if? Oh, what if? Oh! (x2)
