Paris Hilton wants a baby

Paris Hilton is desperate to have a baby.

The socialite -- who is currently accompanying boyfriend Benji Madden on tour with his band Good Charlotte -- wants to follow in best friend Nicole Richie's footsteps by settling down and starting a family.

But Nicole -- who is engaged to and has a baby with Benji's twin brother and bandmate Joel -- is said to have accused the hotel heiress of copying everything she does.

A source told Britain's Star magazine: "Nicole was already upset when Paris started dating Benji - it all happened too fast for her liking. Then Nicole couldn't go on tour with them because she had to stay home and look after her young daughter Harlow.

"She is furious Paris is out there gallivanting with her boyfriend and his brother. If Paris gets pregnant, Nicole is going to go ballistic. She thinks Paris copies everything she does."

Last year, Paris, 27, revealed her desire to have children -- and that she was preparing her body so it was in prime condition to conceive.

"I want kids next year, so I've got to get my body ready," she said.
