You've always been this way since high school    Flirtatious and quite loud    I find your sense of humor spiteful    It shouldn't make you proud       And I know your pretty face gets far with guys    But you make up aint enough to hide the lies       (Chorus)   Are you sure that you're mine    Aren't you dating other guys    'Cos you're so cheap and I'm not blind    You're not worthy of my time    Somebody saw you sleep around the town    And I got proof because the words going around       You left your phone so I invaded    I hated what I saw you stupid lying bitch, who's David?    Some guy who lives next door    So go live in the house of David if you like    But be sure he don't know Peter or John or Mike       (Chorus)   Are you sure that you're mine    Aren't you dating other guys    'Cos you're so cheap and I'm not blind    You're not worthy of my time    Somebody saw you sleep around the town    And I got proof because the words going around       Dont know you    Ooh-ooh-ooh oh woah-oh-oh       And now that you try    To break me into pieces    And I know what you're like    But you can't hurt me now I'm over you       Ooh-ooh-ooh oh woah-oh-oh    Dont like you-ooh    Ooh-ooh-ooh oh woah-oh-oh       (Chorus)   Are you sure that you're mine    Aren't you dating other guys    'Cos you're so cheap and I'm not blind    You're not worthy of my time    Somebody saw you sleep around the town    And I've got proof because the words going around       Don't like you    Ooh-ooh-ooh oh woah-oh-oh    Don't like you    ooh-ooh-ooh oh woah-oh-oh    Don't know you
