She wore a short black dress with long sleeves and a low neckline in the photo shared to her account.

Nicky captioned the share with: “They say the best things in life come in threes. 👶👶👶”

Nicky is already a mom to daughters Lily-Grace Victoria, 5, and Theodora "Teddy" Marilyn Rothschild, 4, whom she shares with husband James Rothschild, 37.

Mom Kathy and sister Paris Hilton are also not aware of the gender of Nicky’s unborn baby.

Kathy told Andy Cohen on his show: “I don't think they're going to find out. We never did, so, I don't know, whatever floats your boat.”

Nicky shared her struggles and the things she’s grateful for during the pandemic in an interview.

She told Interview Magazine: “Well, this past year I, unbeknownst to me, became a nursery school teacher, which I had not planned on. But this time I’ve spent with my family has has been the silver lining of this whole pandemic for me.”
