Lyrics: If your lips are moving, If your lips are moving If your lips are moving, then you're lyin', lyin', lyin', baby If your lips are moving, if your lips are moving If your lips are moving, (I said) then you're lyin', lyin', lyin', baby Boy, look at me in my face Tell me that you're not just about this bass You really think I could be replaced Nah, I come from outer space And I'm a classy girl, I'ma hold it up You're full of something but it ain't love And what we got, straight overdue Go find somebody new You can buy me diamond earrings and deny-ny-ny, ny-ny-ny, deny-ny But I smell her on your collar so goodbye-bye-bye, bye-bye-bye I know you lie (lie) 'Cause your lips are moving (moving) Tell me do you think I'm dumb? I might be young (young), but I ain't stupid (stupid) Talking 'round in circles with your tongue I gave you bass (bass), you gave me sweet talk (sweet talk) Saying how I'm your number one But I know you lie (lie) 'Cause your lips are moving (moving) Baby, don't you know I'm done? (Hey) If your lips are moving, if your lips are moving If your lips are moving, then you're lyin', lyin', lyin', baby (hey) If your lips are moving, if your lips are moving If your lips are moving, then you're lyin', lyin', lyin', baby (hey) Hey, baby, don't you bring them tears 'Cause it's too late, too late, baby, oh (hey) You only love me when you're here You're so two-faced, two-faced, babe (oh) You can buy me diamond earrings and deny-ny-ny, ny-ny-ny, deny-ny (Yes, you can, babe) But I smell her on your collar so goodbye-bye-bye, bye-bye-bye (hey) I know you lie (lie) 'Cause your lips are moving (moving) Tell me do you think I'm dumb?
