Proud auntie moment! The star of The Real Housewives of Beverly Hills Kyle Richards took to her Instagram account late last night to be the very first to wish her beloved niece, model and entrepreneur Paris Hilton, a very happy birthday in honor of her 40th birthday!

Richards also shared a series of photos of the aunt and niece duo, even giving us an intimate look at some adorable snaps of baby Paris! "Happy almost birthday @parishilton (wanted to be the first to post 😆) you made me an aunt when I had just turned 12," said the proud aunt and reality star.

She then gave us a sneak peak at some great memories they have shared together saying, "You taught me what it was like to love and nurture a baby. We lay in bed at night, cuddling side by side. And I learned what it felt like to love someone so much it hurt. I never knew when you grew up we would look like twins".

Richards has always had a very close relationship with all her nieces both from her sister Kathy Hilton's side as well as Kim Richards'. Her sisters' kids are frequently featured on the 'RHOBH' show, and fans have practically watched them all grow up together!

In October of last year, Paris released an intimate documentary entitled 'This Is Paris' detailing abuse she had sustained during boarding schools.
