Shhhhh...! Man I wouldve left my tail at home If I wouldve known that you'd be here We're both here with someone new And they have no clue how I had you dear. I wouldve left my tail at home If I wouldve known that you'd be here You would be here, you would be here! I see that you have a brand new name That's what's up, that's what's up! And something's sparkling on your hand! That's what's up, that's what's up! I wonder why you keep looking this way You know what's up, You know what's up! Are you reminiscent about yesterday? That's what's up, that's what's up! [Chorus:] I wouldve left my tail at home If I wouldve known that you'd be here We're both here with someone new And they have no clue how I had you dear. I wouldve left my tail at home If I wouldve known that you'd be here You would be here, you would be here! They say they that time could heal all wounds ... That's what's up, that's what's up! And you smile when the DJ played our tune That's what's up, that's what's up! I remember you had an appetite... So what's up, U know what's up! But I hope that he fulfills you right That's what's up, that's what's up! [Chorus:] I wouldve left my tail at home If I wouldve known that you'd be here We're both here with someone new And they have no clue how I had you dear. I wouldve left my tail at home If I wouldve known that you'd be here You would be here, you would be here! Now my girl's curious cause my eyes' on you That's what's up, I mean that aint what's up Cause I got caught up on how you used to do Yeah what's up, that's what's up My boy taps me and says Aint that so and so I know what's up, I know what's up I say yeah, but come on, keep that on the low! That's what's up, I know what's up I'm talking reckless, but it's just my ego I understand that we had to let things go, oh You seem happier now Can tell it by your smile... [Chorus:] I wouldve left my tail at home If I wouldve known that you'd be here We're both here with someone new And they have no clue how I had you dear. I wouldve left my tail at home If I wouldve known that you'd be here You would be here, you would be here! And we're both standing in the valet line... That's what's up, that's what's up And your man is car is in front of mine That's what's up, that's what's up S500 guess he's doing well I guess he paid for your weaves and your nails, babe! [Chorus:] I wouldve left my tail at home If I wouldve known that you'd be here We're both here with someone new And they have no clue how I had you dear. I wouldve left my tail at home If I wouldve known that you'd be here You would be here, you would be here!
