Mr. Lonely - Akon

I have been listening to this song since morning and I cannot get around the part of

Lonely I'm Mr Lonely,
I have nobody,
For my owwnnn
I'm so lonely, I'm Mr. Lonely
I have nobody,
For my owwnnn
I'm so lonely,..

I don’t know who sung this part in the song, but the bit is simply catchy. Rest of the song is good too… but then, what exactly is that voice or what is that sort of singing called? :)

Lonely I'm Mr Lonely,
I have nobody,
For my owwnnn
I'm so lonely, I'm Mr. Lonely
I have nobody,
For my owwnnn
I'm so lonely,

Yo, this one here, goes out to all my playas out there ya kno got that one good girl whose always been there like ya
Kno took all the bullshit then one day she cant take it no more and decides to leave

I woke up in the middle of the night and I noticed my girl wasn't by my side, coulda sworn I was dreamin, for her, I was
Feenin, so I hadda take a little ride, back tracking ova these few years, tryna figure out wat I do to make it go bad, cuz
Ever since my girl left me, my whole life came crashin and

I'm so lonely (so lonely),
I'm Mr. Lonely (Mr. Lonely)
I have nobody (I have nobody)
To call my own (to call my own) girl

I'm so lonely (so lonely)
I'm Mr. Lonely (Mr. Lonely)
I have nobody (I have nobody)
To call my own (to call my own) girl

Cant belive I hadda girl like you and I just let you walk right outta my life, after all I put u thru u still stuck
Around and stayed by my side, what really hurt me is I broke ur heart, baby you were a good girl and I had no right, I
Really wanna make things right, cuz without u in my life girl

I'm so lonely (so lonely)
I'm Mr. Lonely (Mr. Lonely)
I have nobody (I have nobody)
To call my own (to call my own) girl

I'm so lonely (so lonely)
I'm Mr. Lonely (Mr. Lonely)
I have nobody (I have nobody)
To call my own (to call my own) girl

Been all about the world ain't neva met a girl that can take the things that you been through
Never thought the day would come where you would get up and run and I would be out chasing u
Cuz aint nowhere in the globe id rather be, aint noone in the globe id rather see then the girl of my dreams that made me
Be so happy but now so lonely

So lonely (so lonely)
I'm Mr. Lonely (Mr. Lonely)
I have nobody (I have nobody)
To call my own (to call my own)

I'm so lonely (so lonely)
I'm Mr. Lonely (Mr. Lonely)
I have nobody (I have nobody)
To call my own (to call my own) girrll

Never thought that id be alone, I didnt hope you'd be gone this long, I jus want u to call my phone, so stop playing girl and
Come on home (come on home), baby girl I didn't mean to shout, I want me and you to work it out, I never wished Id ever
Hurt my baby, and its drivin me crazy cuz...

I'm so lonely (so lonely)
I'm Mr. Lonely (Mr. Lonely)
I have nobody (I have nobody)
To call my own (to call my own)

I'm so lonely (so lonely)
I'm Mr. Lonely (Mr. Lonely)
I have nobody (I have nobody)
To call my own (to call my own) girll

Lonely, so lonely
So lonely, (so lonely),
Mr. Lonely, so lonely
So lonely, so lonely, (so lonely), Mr. Lonely
