Hilton added: "Can't wait to make new memories together at my favorite @Hilton."

The 43-year-old entrepreneur and socialite shared her first photos of her infant daughter on Instagram in April. In the family pictures, her then-4-month-old wore a blush pink sweater over a matching tutu skirt and a pink bow headband while Hilton held her in a sundress with yellow flowers.

"Introducing London Marilyn Hilton-Reum💕👶🏼💕 I've dreamed of having a daughter named London for as long as I can remember," she captioned the post. "I'm so grateful she is here😍 I truly cherish every moment I spend with her."

Hilton also included group photos with Reum, 43, and their 1-year-old son Phoenix.

"Together with Phoenix, my angel babies have shown me a love that I never even knew could run so deep before I became their mother," the mom-of-two gushed in her caption.

Hilton made the conscious choice not to share photos of her daughter until it felt "the time right," she told E! News in April.

"I feel like my life has just been so public with everything," the reality TV alum explained. "So I just wanted to keep my little girl to me. But I'm gonna show her to the world soon 'cause everyone keeps asking."

Hilton's son Phoenix was bullied on social media for his appearance in October, leading the socialite to call out the negativity.

"My angel is perfectly healthy. And yes, of course he has been to a doctor, he just has a large brain," she wrote on her Instagram story at the time, adding, "Living life in the spotlight, comments are inevitable, but targeting my child, or anyone else's for that matter, is unacceptable."

Hilton added that she is often questioned about her parenting based on her social media. "If I don't post my baby, people assume I'm not a great mother and if I do post him, there are some people who are cruel and hateful," she wrote. "I'm a proud working mom and my baby is perfectly healthy, adorable and angelic.
