Sara Jaye Weiss/Shutterstock Pregnant Nicky Hilton Rothschild Wears Floral Maxi Dress at Frida Mom Event — See Her Baby Bump! Last month, the fashion designer joined new and expecting moms for a Frida Mom event held at her mom Kathy Hilton's estate. For the celebration, Hilton Rothschild wore a hot-pink floral maxi dress that hugged her baby bump. She paired the look with a pair of pink strappy heels and an emerald green ring. Hilton Rothschild said last month that she "maybe" won't find out the sex of the baby ahead of his or her birth, on the advice of her mom Kathy. "My mom's very old-fashioned. She's like, 'I didn't find out for any of you kids. Please, it's the ultimate surprise in life, do not find out,' " she told E! News during New York Fashion Week. Hilton Rothschild also said she feels "pretty prepared," given that she has had two children already. "I do have to start getting the room ready," she added.
