Hilton and Richie make up?

Socialite Paris Hilton is reportedly attempting to make amends with her estranged best pal Nicole Richie, after a nine month feud.

The Simple Life co-stars mysteriously fell out in January, with Hilton later declaring: "It's no big secret that Nicole and I are no longer friends. I will not go into the details of what happened. All I will say is that Nicole knows what she did and that's all I am ever going to say about it."

However British website FemaleFirst.co.uk claims Hilton has attempted to reconcile with Richie after admitting she has been "petty".

A friend says, "Paris just wanted to call things a day after friends stepped in and told her she was being petty."

The partygirls' reality TV show is currently looking for a new channel after Fox dropped the programme last week.
