The Real Housewives of Beverly Hills veteran opened the doors to her stunning home she shares with husband Rick Hilton.

It was an afternoon party to launch the design-forward home goods brand Ruggable.

‘Inspired by The Hiltons’ and their love of entertaining, this collection makes it easier than ever to create a chic space perfect for hosting, and Wednesday’s party celebrated just that,’ a press release shared.

Each rug is named after a place or past home that holds special importance for Kathy and Nicky: The Brooklawn is named after Nicky’s grandfather’s estate, The Astoria is inspired by the Hiltons’ long-time residence at The Waldorf-Astoria, and The Chrysler is inspired by Kathy’s favorite view when living in NYC.

This comes after it was said Paris and pal Nicole Richie ‘haven’t changed’ since The Simple Life.

The celebrity duo starred in the hit reality TV series for five seasons, and Lionel Richie – Nicole’s dad – believes they’ve hardly changed in the last 20 years.

Lionel, 74, told ‘Entertainment Tonight’: ‘They haven’t changed.

‘Let me tell you something, those two scare me just standing next to each other. And I don’t know if the world knows this, they started this mess, and I was the first guinea pig daddy to go along with this.’

Paris, 43, and Nicole, 42, recently teased a new TV project.

Lionel, meanwhile, still has vivid memories of their time on The Simple Life.
