The soon-to-be parents-of-three tied the knot in the summer of 2015 at Kensington Palace and share daughters Lily Grace Victoria, 5, and Theodora "Teddy" Marilyn, 4.
Nicky, 38, previously gushed over being a mom in the pandemic, explaining during a Q&A with childrenswear brand Dotty Dungarees that she loved the extra time she got to spend with her daughters.
"I strangely liked the not leaving the house for days at a time. There was something so cozy about being locked down with my family," she reportedly shared. "That quality family time was definitely the silver lining of the pandemic."
And after welcoming her second child not too long ago, Nicky got real about the biggest lesson she's learned since becoming a parent, telling People: "Patience and being the best version of yourself."
As Nicky gets ready to expand her family once more, it seems her older sister is following close behind.
Paris Hilton, 40, spilled on E! News' Daily Pop on Monday, January 25, that she has babies on the brain, revealing that having a child is "definitely one of my top priorities." Though the Paris In Love star and new hubby Carter Reum only tied the knot in November, they're already ready to welcome "two or three" kiddos.
"I would want twins first," she reportedly added. "I don't know it's hard to say. I always wish I had an older brother because I feel like if I did then he would protect me and things like that in school."
Paris revealed last January that she began the in vitro fertilization (IVF) process and praised Reum for being "so supportive."
