With the debut of mom Kathy Hilton’s new fragrance Kathy Hilton My Secret hot on the heels of Paris‘s latest scent Can Can, the Hiltons have become the first mother-daughter duo to have fragrances out at the same time. And at a special brunch to launch the new scent, Kathy joked to PEOPLE, “I told [Paris], if she buys my retail, I’ll buy her retail!” To celebrate the launch, Kathy held a contest on her website to win a special brunch with all Hilton women. The winners, mother Kelly and daughter Katie Mills were flown from their hometown of Cleveland to L.A. for a day of dining, makeovers and — of course — a little shopping, guided by expert shoppers Paris, Nicky and Kathy!
