(Verse 1) Sitting up in the club Sitting up every-night Seeing you with him in the club (In the club) Every Friday night (Every Friday night) Oh, how my heart breaks, doesn't matter though (It doesn't matter) Sitting up in the club every Friday night... (Chorus 1) Baby, you cheated on me for the last time You won't ever see me again Doesn't matter though, my hearts not broken I'm gonna keep grinding it up, grinding it up, baby Grinding it up, grinding it up, you cheated on me But I don't care I'm gonna keep grinding it up, grinding it up, baby I don't care, baby (I don't care) (Verse 2) Baby, you didn't seem to care About all the attention I gave to you (All to you) Guess a little love can't fix an already broken heart (Broken heart) Doesn't matter though, that won't stop me (No it won't, no it won't) (Chorus 2) Baby, you cheated on me for the last time You won't ever cheat on anyone again Doesn't matter though, my hearts not broken I'm gonna keep grinding it up, grinding it up, baby Grinding it up, grinding it up, you cheated on me But I don't care (Bridge) You cheated on me Baby, how'd you do it? (How'd you do it, babe?) Do you not have a heart? (Chorus 3) Baby, you cheated on me for the last time You won't ever see me again You won't cheat on anyone ever again Doesn't matter though, my hearts not broken I'm gonna keep grinding it up, grinding it up, baby Grinding it up, grinding it up I don't care Baby, you cheated on me for the last time
