The Simple Life co-stars mysteriously fell out in January (05), 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 (ends14OCT05).
