There's no denying that Kyle Richards and her niece, Paris Hilton, are close. And on Paris' 35th birthday, the Real Housewives of Beverly Hills aunt shared a touching message about the former reality star and socialite. "Happy birthday to my beautiful niece @parishilton the baby sister I never had. Love you so much," she wrote on Instagram on Wednesday. Sure, Kyle has two older sisters, Kim Richards and Paris' mom Kathy Hilton, but given that she's only 12 years older than her niece it should be no surprise that she thinks of her as a younger sibling.
Kyle wasn't the only one feeling the love for Paris on her milestone birthday. Her younger sister, Nicky, also shared a birthday wish for the fashionista.
And, of course, Paris celebrated herself by feeling nostalgic on Instagram via a series of throwback photos from celebrations past.
And this year, in case you're keeping score, she's heading to "paradise" to celebrate. Um, can we drop by to buy you a birthday cocktail? That would be so hot.
