Richie was busy working on her segment of the reality series at a Beverly Hills toyshop, when the crew were stopped by police and caught filming without a licence.
An insider told the Daily Star, "Paris is livid that this episode with Nicole has disrupted plans for her work on the series. It probably all stems from residual bitterness between them.
"Paris thinks Nicole should've checked that they had a permit, but what star does that? It's down to their crew, pure and simple."
