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 the

Than hang around and stare at me and complicate mine?"

Meanwhile, Hilary Duff is defending celebrities who go under the knife.

Duff, who has had a little work done to her own teeth, admitted that she has not ruled out giving nature a helping hand when she gets older.

According to The Sun UK, Duff said: "I don't have anything against people who have surgery. If I get older and feel uncomfortable about something then maybe I will have it. I never say never."

"Some things are hard to deal with for a woman as you grow older. I think everyone should be able to feel good about themselves.

"I don't like it when it's really obvious and gets pointed out. Some people go overboard."

"I do worry about what I look like but I'm not going to let it control my life. If I want to go to the shops I'll sometimes not bother with my hair or make-up."
