Paris and Phoenix were joined by Nicky Hilton and her two daughters for the holiday outing to the California theme park

Paris Hilton and her son Phoenix are celebrating Christmas at the "happiest place on Earth!"

On Sunday, the Paris in Love star, 42, posted a carousel of photos on Instagram documenting Phoenix's first visit to Disneyland, an experience she described as "a dream come true."

She went on to share just how special it was to watch her son, who turned 11 months old on Christmas Eve, react to the Disney magic and wonder all around him.

"Absolutely magical and incredibly heartwarming🥹," Paris wrote in her caption. "Watching his excitement and awe at every new sight and sound, it’s clear why this place is known as the happiest on Earth."

"These precious moments of pure joy and wonder will stay in my heart forever🥰," continued the "Stars Are Blind" singer, who is also mom to daughter London Marilyn, 6 weeks. "It’s moments like these that make life so beautiful and remind us why Disneyland is truly the happiest place on Earth✨🥹❤️👶🏼🏰✨."

In the photos, Hilton and her son — who were accompanied by Hilton's husband, Carter Reum — could both be seen dressed for the occasion.

Phoenix wore a Christmas-themed Mickey Mouse outfit and ears, while his mom wore ears with furry pom-poms and carried a Minnie Mouse-inspired polka-dot bag.

Hilton's sister, Nicky Hilton, also came along for the fun, bringing her daughters, Lily-Grace Victoria, 7, and Theodora "Teddy" Marilyn, 6. One photo captured Paris, Nicky and the three cousins posing together by a Christmas tree.

In another sweet image, Paris lovingly cradled Phoenix against her chest as she closed her eyes and soaked up the moment.

On Friday, Paris shared her family Christmas photos exclusively with PEOPLE. She, Reum, 42, and their two children dressed in matching red plaid pajamas as they posed together on a staircase surrounded by pink floral arrangements. Paris' chihuahua even got in on the action, appearing in several shots wearing a tiny, Santa-style outfit.

"Carter and I couldn’t wait to take our very first holiday photo with Phoenix and London, as a family of four," Paris told PEOPLE. "I’ve always dreamt of this moment and we can’t wait to start our own family traditions, celebrate the holidays and ring in the new year."

"I feel so lucky and blessed to have this beautiful family and life together," she added.

"When your baby loves puppies as much as you do," Paris wrote in the caption, a nod to her well-documented love for her dogs.
