Paris Hilton Celebrates First Mother's Day as a Mom of 2: 'My Heart Is So Full Today'

Hilton shares her kids — son Phoenix, 16 months, and daughter London, 5 months — with husband Carter Reum

Paris Hilton is celebrating a very special Mother's Day as a mom of two!

On Sunday, May 12, the multi-hyphenate shared a video on Instagram to mark the occasion, featuring never-before-seen moments between herself and son Phoenix Barron, 16 months, and daughter London Marilyn, 5 months, whom she shares with husband Carter Reum.

The video — set to Hilton's song with Sia, "Fame Won't Love You" — begins with a shot of the reality star and Reum, 43, holding their two children while sitting on a picnic blanket. There's also a sweet clip of Reum moving Phoenix's arms around like he's dancing during a photo shoot.

Hilton highlights her mother-son bond as the two play together and flail their feet in the pool in one short clip, while another shows just how ecstatic Hilton is to be a girl mom as she smiles down at her daughter.

She also shared individual videos of London playing with her favorite doll and Phoenix having fun in the pool and with the family's dogs. There's even a quick snippet of the brother-sister duo together, with Phoenix gently rocking his sister's chair.

"My first Mother’s Day as a mom of two! My heart is so full today 🥹💖," she captioned the photo, adding, "Use #FameWontLoveYou in your Mother’s Day posts so I can see all of your beautiful families 🥰."

Speaking to PEOPLE after the birth of son Phoenix, Hilton said, "It's always been my dream to be a mother," adding that she and Reum, who welcomed both of their kids via surrogate, "are so excited to start our family together and our hearts are exploding with love for our baby boy."

Elsewhere in the interview, the heiress and media personality shared what she found to be the most surprising part of motherhood.

“It's just how much love I could have for someone,” Hilton said. “I thought I knew what love was with my husband, but as soon as I met my baby, it's just this love on another level. He has just changed my life in every way."

Hilton's journey to motherhood was shrouded in secrecy, with the DJ opening up about the efforts she took to keep her son’s birth a secret, even wearing a disguise to the hospital and not telling anyone (including family members) about his arrival.

Speaking on her podcast I Am Paris in February 2023, Hilton said she waited until a week after Phoenix’s birth to share the news with her friends and family.

“Not even my mom, my sisters, my best friend knew until he was over a week old,” she said on the podcast. “It was really nice to have that with Carter, be our own journey together. I just feel like my life has been so public, and I've never really had anything be just mine."

Last year on Mother's Day, Hilton took to social media to share her gratitude, writing on X: "So excited to be celebrating my first Mothers Day with my little angel baby Phoenix. Being a mom is the most incredible experience I have ever had. It's a love that cannot be put into words, a feeling that I never knew existed until I held my little prince in my arms."

Hilton added that watching Phoenix "grow and learn every single day brings me so much happiness and fills my heart with so much love. There is something so special about being a mom, something that I never fully understood until I became one myself."
