Hilary Duff apparently slams ex-lover Joel Madden (left) and his girlfriend Nicole Richie on her new album. In the title track of 'Dignity', the blonde singer appears to attack the couple who began dating soon after the Good Charlotte frontman split from Hilary.The song lyrics apparently say: "Where's your dignity? I think you lost it in the Hollywood Hills. Can't buy respect but you can pick up that bill. Always with Mr. Right, but then you have a fight. Run into your friend's ex,he's happy to be your next. Tomorrow's paper's coming out so kiss him fast, watch the cameras flash."Hilary, who dated Joel for two years, is also said to slate Nicole on track 'Gypsy Woman' - branding 'The Simple Life' star "sick" and "shameless".The lyrics read: "She lets you think that you found her first. That's how she works her sick and twisted gypsy curse. Talks with a grin 'cause she's got no shame. Enjoy the fame, bringing down the family name."Joel and Nicole are not the only ones on the end of a verbal attack from the19-year-old singer. In 'Dreamer', Hilary seemingly condemns the man who was jailed in January for stalking her. Hilary allegedly sings: "Don't you have better things to do with your life.Than hang around and stare at me and complicate mine?"
