(What your girl don"t know) 
(What your girl don"t know) 
Hanging round, trying to talk to me 
but I know, "bout your history 
when it comes to playing games 
you should be in the hall of fame 

I"m not the kind of kiss 
I"m not the kind of tell 
but there"s one thing I know very well 
You"ve got someone else waiting home for you 
You"re playing her for a fool 

What your girl don"t know 
that when she turns her back you"re talking to me 

What your girl don"t know 
that everything aint what it seems to be 

What your girl don"t know 
all your little games and your lies 
she should know better but she doesn"t realise 
I can write a book about everything your girl don"t know 

I can"t deny you qualify 
you"ve played the part a hundred times 
but that was then and this is me 
I"ll make it clear so that you can see 

Now what goes around will come back around 
time will tell what you"re all about 
you can try to be who you want to be 
but everybody can see what your girl don"t know 

(What your girl don"t know) 

What your girl don"t know 
that when she turns her back 
you"re talking to me 

What your girl don"t know 
that everything aint what it seems to be 

What your girl don"t know 
all your little games and your lies 
she should know better but she doesn"t realise 
I can write a book about everything your girl don"t know 

(uh oh) 

So sad, it"s a crying shame 
too bad you"re the one to blame 
Won"t be long, til you feel the pain 
all alone in the pouring rain 
Gonna to get what"s coming to you 
Gonna to pay for everything you do 
One thing that I know is true 
it"s gonna catch up to you 

What your girl don"t know 
that when she turns her back 
you"re talking to me 

What your girl don"t know 
that everything aint what it seems to be 

What your girl don"t know 
all your little games and your lies 
she should know better but she doesn"t realise 
I can write a book about everything your girl don"t know 

I"m not the kind of kiss 
I"m not the kind of tell 
but there"s one thing I know very well 
You"ve got someone else waiting home for you 
You"re playing her for a fool 
(What your girl don"t know) 
now what goes around will come back around 
time will tell what you"re all about 
(What your girl don"t know) 
you can try to be who you want to be 
everybody can see what your girl don"t know 
(What your girl don"t know) 
all your little games and your lies 
she should know better but she doesn"t realise
