VERSE 1 You know this isn't right Calling me at night While she's lying In your bed Your phone is by your side You better change your mind I won't be picking up again BRIDGE Why you looking at me to be the next one When you're not even done with the last one What you've done to her I just don't deserve. CHORUS I'll make this easy for you You shouldn't be confused You never had me to lose So you don't have to choose Does she know you're single? Does she know you're single? Does your girlfriend know you're single? VERSE 2 Shes waiting in the car While you're in the bar Spilling lines like Casanova I want my Romeo No lethario So your winning streak is over BRIDGE Why you looking at me to be the next one When you're not even done with the last one What you've done to her I just don't deserve. CHORUS MIDDLE 8 So next time I'm on your mind Don't you start to walk that line CHORUS Does she know Does she know Does she know you're single? X2
