[Intro: Tom Higgenson]
Whoa-oh, whoa-oh, whoa-oh
(That side of your bed is still mine)
Whoa-oh, whoa-oh, whoa-oh
(That side of your bed is still mine)

[Verse 1: Ashlee Simpson]
Am I the reason why you tossed
And turned last night?
Everything's such a blur
It didn't come out right
All of the sudden it's cold
And we're falling apart
No, this can't be
Please don't leave me alone in the dark

[Chorus: Ashlee Simpson & Tom Higgenson]
And I guess we're really over
So come over, I'm not over it
And I guess we're really over
So come over, I'm not over it
Late night you make me feel
Like I'm desperate, I'm not desperate (Oh)
A little bit possessive, little miss obsessive
Can't get over it
[Post-Chorus: Tom Higgenson]
Whoa-oh, whoa-oh, whoa-oh
(That side of your bed is still mine)
Whoa-oh, whoa-oh, whoa-oh
(That side of your bed is still mine)

[Verse 2: Ashlee Simpson]
I've never been a fan of long goodbyes
I'm at the finish line
And you're just way too far behind
In the morning, I got in a fight with myself
I got the bruises to prove it
Then I swallowed your words
And spit them right back out

[Chorus: Ashlee Simpson & Tom Higgenson]
And I guess we're really over (Over)
So come over, I'm not over it
And I guess we're really over (Over)
So come over, I'm not over it
Late night you make me feel
Like I'm desperate, I'm not desperate (Oh)
A little bit possessive, little miss obsessive
Can't get over it, no

[Bridge: Ashlee Simpson & Tom Higgenson]
It's like a fairy tale without a happy ending (Happy ending)
But then again, maybe we are just pretending
Why does it have to be so unfair?
Tell me that you care
[Chorus: Ashlee Simpson & Tom Higgenson]
And I guess we're really over
But come over, I'm not over it
And I guess we're really over
So come over, I'm not over it, oh

[Break: Tom Higgenson]
Little miss (Woah), little miss (Woah)
Little miss (Woah), little miss obsessive
Little miss (Woah), little miss (Woah)
Little miss (Woah), little miss obsessive

[Chorus: Ashlee Simpson & Tom Higgenson]
Late night you make me feel
Like I'm desperate, I'm not desperate (Oh)
A little bit possessive, little miss obsessive
Can't get over it, no

[Outro: Tom Higgenson]
Whoa-oh, whoa-oh, whoa-oh
(That side of your bed is still mine)
Whoa-oh, whoa-oh, whoa-oh
(That side of your bed is still mine)
