Kathy Hilton and Paris Hilton made it a hunky dory family affair! The Real Housewives of Beverly Hills mom and her socialite daughter opened up about all things family, including Nicky Hilton Rothschild's recent pregnancy announcement, during their January 26 appearance on Watch Watch Happens Live with Andy Cohen.

After host Andy Cohen congratulated Kathy and Paris about Nicky's exciting news (she and hubby James Rothschild just revealed they're expecting their third child this summer) he asked if either of them knew yet if Nicky was expecting a boy or a girl. "I don't think they're going to find out," Kathy replied, adding, "We never did, so, I don't know, whatever floats your boat."

Andy then asked Paris, who recently wed Carter Reum in November of last year and is sharing her happily-ever-after journey on the Peacock original series Paris in Love, if she has considered growing her family, asking, "Is it something that you want?"

Paris answered with no hesitation: "Definitely." She went on to add, "Now, with Nicky's news, I can't wait so they can all grow up together."

This isn't the first time Paris has been vocal about wanting kids. The subject recently came up during a January 25 appearance alongside her hubby on The TODAY Show where the newlyweds were asked whether they had plans to start a family. “Yes, we cannot wait," Paris replied, adding, "We are so excited for that — very soon.”

Recently, Paris took to Instagram to share her happiness about becoming an aunt for the third time and to show love to her mom-to-be little sister, Nicky. "I’m so so happy for my sister [Nicky] and her husband James on the announcement of their third child on the way!" she captioned the January 25 post, which featured an adorable throwback capture of Paris holding baby Nicky.

Paris went on to add, "You are the best mom and I love being an aunt to your two beautiful angels, and can’t wait to meet your new baby! Love you all so much!"
