Paris Hilton is reportedly desperate to have a baby.

The 'Simple Life' star - who is currently accompanying her Good Charlotte
rocker boyfriend Benji Madden on tour - wants to follow in best friend
Nicole Richie's footsteps by settling down and starting a family.

However, Nicole - who is engaged to Benji's twin brother and bandmate Joel -
is said to have accused Paris of copying her every move.

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 revealed she was preparing her body so it was in prime
condition to conceive.

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

Back in June 2005 Paris was dating Paris Latsis. In an interview with Newsweek almost 3 years ago she revealed her plans to settle down.

NEW YORK - Paris Hilton plans to give up public life for family life. The 24-year-old hotel heiress, star of "The Simple Life" reality series, tells Newsweek magazine:

"I thought it was cute to play a dumb blonde. On TV, I do it because it's funny. I consider myself a businesswoman and a brand."

But Hilton says she plans to give up her public life in two years, by which time she expects to become a mother with her fiance, Paris Latsis.

"I don't enjoy going out anymore," she says.

"It's such a pain. It's everyone saying, `Let's do a deal! Can I have a picture?' I'm just, like, `These people are such losers. I can't believe I used to love doing this.'"

Paris might never get to have kids.
