Nicky Hilton has banned her sister Paris from visiting her new Los Angeles mansion - in case her older sibling copies her decor.

The socialite-turned-fashion designer recently purchased a new home and has just put the finishing touches to the interior design. However Hilton is determined to preserve its individuality from the prying eyes of her elder sister.

She says, "'I told her she isn't allowed to come over if she copies me. I don't want my house to look like a page you see in a catalogue. I like drama when it comes to design."
