[Verse 1: Justin with JC, All]

I just don't understand

Why you're runnin' from a good man, baby

Why you wanna turn your back on love

Why you've already given up

See I know you've been hurt before

But I swear I'll give you so much more

I swear I'll never let you down

'Cause I swear it's you that I adore

[Pre-Chorus 1: Justin with JC, All]

And I can't help myself, babe

'Cause I think about you constantly

And my heart gets no rest over you

You, you, yeah, yeah

[Chorus: Justin, All]

You can call me selfish

But all I want is your love

And you can call me hopeless (Hopeless), baby

'Cause I'm hopelessly in love

You can call me un-perfect

But who's perfect?

Tell me what do I gotta do

To prove that I'm the only one for you?

(To prove that I'm the only one)

So what's wrong with bein' selfish?

Yeah, yeah, yeah

[Verse 2: JC with Justin, with All]

I'll be takin' up your time

'Til the day I make you realize (Realize)

That for you, there could be no one else

I've just gotta have you for myself (For myself)

Baby, I will take good care of you (Good care)

No matter what it is you're goin' through

I'll be there for you when you're in need

Baby, believe in me

[Pre-Chorus 2: JC, All]

'Cause if love is a crime, hey yeah

Then punish me, I would die for you

'Cause I don't want to live without you

What can I do? Oh oh

[Chorus: JC, All]

You can call me selfish

But all I want is your love

And you can call me hopeless (Hopeless), baby

'Cause I'm hopelessly in love

You can call me un-perfect

But who's perfect?

Tell me what do I gotta do

To prove that I'm the only one for you? (To prove that I'm the only one)

[Bridge: Justin, JC, All]

Why do you keep us apart?

Why won't you give up your heart?

You know that we're meant to be together

And why do you push me away?

All that I want is to give you love

Forever and ever and ever (Forever and ever and ever)

[Chorus: JC, Justin, All]

You can call me selfish

But all I want is your love

You can call me hopeless (Hopeless), hopeless

Because I'm hopelessly in love

You can call me unperfect

But who's perfect?

Tell me what do I gotta do

To prove that I'm the only one for you?

(To prove that I'm the only one) Oh

[Middle 8: All, Justin, JC]

Selfishly I'm (Hey yeah) In love with you (Oh)

'Cause I've searched my soul (Searched my soul, baby)

And know that it's you

Selfishly I'm (Selfishly I'm) in love with you

'Cause I've searched my soul (Searched my soul down deep inside)

And know that it's you

Selfishly I'm in love with you (I'm so in love with you)

'Cause I've searched my soul

And know that it's you

I'll prove that I'm the only one for you

[Outro: JC, Justin]

So what's wrong with being selfish, selfish, selfish?

So what's wrong with being selfish? Yeah
