I've been feeling like you ain't been happy in a while 
I've been thinking of things I could do to make you smile, yeah 
But when I get home and it's just the same, oh no no 
Why did I find you in another man's arms, oh 

Oh why, i'm not the type to play these games so 
Oh I, don't ever wanna see your face again 

Who is he? 
Where's he from? 
What does he do for you that I couldn't have done? 
What's his name? 
I guess you like his style 
How can you tell me I've been living in denial? 
I can't believe it 
No, no, no 
Just can't believe it 
No, no, no 
Who is he? 

Now you got me twisted don't know what to do 
There's a war in my mind and I know who's gonna lose, yeah 
I can't believe all that work only to see her, oh no, no 
Just to find out you're a straight-up deceiver with a cold demeanour 

You showed a difference why you lied and cheated 
You stole my heart but girl you cannot keep it 

Who is he? 
Where's he from? 
What does he do for you that I couldn't have done? 
What's his name? 
I guess you like his style 
How can you tell me I've been living in denial? 
I can't believe it 
No, no, no 
Just can't believe it 
No, no, no 
I can't believe it 
No, no, no 
Just can't believe it 
No, no, no 
Who is he? 

I've been feeling like you ain't been happy in a while 
I've been thinking of things I could do to make you smile, yeah 

Who is he, where's he from? 
What does he do for you that I couldn't have done? 
What his name? 
I guess you like his style 
How can you tell me I've been living in denial? 

I can't believe it
