The star, her sister Nicky Hilton Rothschild and their mom Kathy Hilton co-hosted the Christmas in September event, a 2021 Toy Drive for Children's Hospital, on Tuesday in Los Angeles. They spoke to Extra during the event, when Paris, 40, shared one worry she has about having a daughter, which she previously revealed she'd name London. "I'm probably going to be a strict mom. I'm just worried for when my baby London says, 'Mom, I want to go on a date, I want to go to a club,' and I'm going to go, 'No,' " she said. Nicky, 37, said Paris is great as an aunt to her two kids, daughters Theodora "Teddy" Marilyn, 3½, and Lily-Grace Victoria, 5: "They adore her. … She's usually in a bubblegum-pink outfit with several … toys, and they just think she's like [a] big Barbie doll."

I didn't even know anything about it." She also said of the egg retrieval procedure, "It was tough, but I knew it would be worth it. I did it a couple of times. Just doing it together and having a partner that is just so supportive and always makes me feel just like a princess all the time ... that it wasn't that bad."
