(femalefirst.co.uk) - 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. 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."
