[Chorus: Jessica Mauboy]
I feel you even though we're apart
And without you there's a hole in my heart
Oh, baby, baby, though I tried I just can't adjust
Oh boy, what happened to us, happened to us, happened to us?

[Verse 1: Jessica Mauboy]
We were in love, we both felt the same
The good thing that we had, boy was insane
We had a bond that would never break
Why we let it go?
Oh, we used to stay all night long
Kissing to our favorite songs
Tell me where it all went wrong
That's what I got to know, whoa-oh, whoa

[Chorus: Jessica Mauboy, with Jay Sean]
'Cause I feel you even though we're apart
And without you there's a hole in my heart
Oh, baby, baby, though I tried I just can't adjust
Oh, boy, what happened to us, happened to us?
I thought that I could get over you
Oh, but baby, that is so far from true
Oh baby, baby, got something I wanna discuss
Oh boy, what happened to us, happened to us, happened to us?
[Verse 2: Jay Sean, Jessica Mauboy, Both]
I think that we oughta work it out
Like air, your love, I can't live without
So have mercy, don't leave me in doubt
Saying "I love" still burns (Still burns, still burns)
I try to go my separate way
At first I thought it was okay
I miss you more with each day
So to you I turn

[Chorus: Jessica Mauboy, Jay Sean, Both]
'Cause I feel you even though we're apart (Hey)
And without you there's a hole in my heart
Oh, baby, baby, though I tried I just can't adjust, no
Oh, boy, what happened to us, happened to us? (Oh-oh-oh)
I thought that I could get over you (Oh, hey)
Oh, but baby, that is so far from true (So far)
Oh baby, baby, got something I wanna discuss, yeah yeah
Oh boy, what happened to us, happened to us, happened to us?

[Bridge: Jessica Mauboy, Jay Sean, Both]
I know that you saw me with someone else
But believe me, I'm all by myself
Ooh...
Yeah yeah, yeah yeah
(Oh boy, what happened to us, happened to us?)
Whoa, whoa, whoa!
[Chorus: Jessica Mauboy, Jay Sean, Both]
'Cause I feel you even though we're apart (Though we're apart)
And without you there's a hole in my heart
Oh, baby, baby, though I tried I just can't adjust (Tried to adjust) (Just can't adjust)
Oh, boy, what happened to us, happened to us? (Girl, what happened to us?) (No)
I thought that I could get over you (Get over you)
Oh, but baby, that is so far from true (So far from true)
Oh baby, baby, got something I wanna discuss (Oh no)
Oh boy, what happened to us, happened to us, happened to us?

[Interlude: Jessica Mauboy, Jay Sean]
Tell me
Yeah

[Outro: Jessica Mauboy, Jay Sean, Both]
'Cause I feel you even though we're apart
And without you there's a hole in my heart
Oh baby, baby though I tried I just can't adjust, no
Oh boy, what happened to us, happened to us? (What happened to us?) (Whoa)
Oh boy, what happened to us, happened to us?
