I've been kickin' it with your girlfriend, what am 
I gonna do?'
Cause, God knows that 
I really didn't mean to hurt you
I know it's bogus, but 
I felt that you should know the truth
I fell in love with her the moment we were introduced
And I just feel that it's time for this little secret to end
Baby, I'm kickin' it with your girlfriend
Oh, oh, oh
Go on and slap me again, 'cause 
I can understand how you feel
When a man takes you for granted and he don't keep it real
I should've been more man and told you a long time ago
Instead of stunnin', 
I should have broke it down and let you know
Girl, my fault for that, don't know what's on my mind
And I blame myself for wastin' your time
Believe, I really tried to keep that girl away from me
But her body language kept on temptin' and teasin' me
And plus, she knew what she was doing and did it anyway
I knew what she was doing, too, and that made it okay
Truth is that we don't even regret it
Up out the closet, 
I will be the first to say it
I've been kickin' it with your girlfriend, what am 
I gonna do?'
Cause, God knows that 
I really didn't mean to hurt you
I know it's bogus, but 
I felt that you should know the truth
I fell in love with her the moment we were introduced
And I just feel that it's time for this little secret to end
Baby, I'm kickin' it with your girlfriend
Oh, oh, oh
Now, I apologize for me and her and everything that went down
These are the reasons why some girls don't bring they friends around
I just didn't know how to tell 
I was feelin' her
And how we would get away sometimes and make love
I never wanted to mislead you
At first I just wanted to please you
I know it's hard for you to be able to trust again'
Cause I came between you and your best friend
I did not ask for this
It just happened outta no where since the day we kissed
And, the truth is that we don't even regret it
Up out the closet, 
I will be the first to say it
I've been kickin' it with your girlfriend, what am 
I gonna do?'
Cause, God knows that 
I really didn't mean to hurt you
I know it's bogus, but 
I felt that you should know the truth
I fell in love with her the moment we were introduced
And I just feel that it's time for this little secret to end
Baby, I'm kickin' it with your girlfriend
Oh, I'm sorry again, never meant to hurt you
I'm sorry again but girl, 
I love her
I'm sorry again, 
I never meant to make you cry, no
Now I'm right out the closet
I've been kickin' it with your girlfriend, what am 
I gonna do?'
Cause, God knows that 
I really didn't mean to hurt you
I know it's bogus, but 
I felt that you should know the truth
I fell in love with her the moment we were introduced
And I just feel that it's time for this little secret to end
Baby, I'm kickin' it with your girlfriend
I've been kickin' it with your girlfriend, what am 
I gonna do?'
Cause, God knows that 
I really didn't mean to hurt you
I know it's bogus, but 
I felt that you should know the truth
I fell in love with her the moment we were introduced
