“Find someone who makes you feel like a kid again,” Hilton wrote alongside a video of her and Reum ‘racing’ on electric suitcase scooters with son Phoenix.

Paris Hilton let her inner child loose for Halloween!

The heiress and entrepreneur, 42, shared a glimpse into how she spent the spooky season with husband Carter Reum and 9-month-old son Phoenix Barron, which included dressing up as Super Mario characters and having a Mario Kart-style showdown at their home.

Hilton shared several photos on Instagram of the family on their doorstep in various poses. She could be seen sporting a Princess Peach costume, with a short pink dress that mimicked the popular video-game royal’s getup, along with a crown, bright-pink pumps and a matching choker.

Her husband donned a red Mario costume, complete with black overalls over a red shirt and a matching red pageboy cap. He held their son Phoenix, who matched with his dad in a Luigi costume with a green shirt, green pageboy cap and denim overalls.

In one adorable shot, the “Stars are Blind” singer bent down to give Phoenix a bright smile as her husband also grinned. In another snap, she sat down on the front steps of their home — decorated with various pumpkins and skeletons — and posed with baby Phoenix on her lap.

Hilton also shared photos from their outdoor Mario Kart race. Her new chihuahua, Prince Tokyo Gizmo Hilton, gave a brief cameo in one snap as she held him while sitting on top of a scooter. She concluded the post with shots of Reum, 42, and Phoenix sporting matching mustaches as the family posed in a room, and a candid snap of the family of three having some fun on the stairs.

“The Mario and Luigi to my Princess Peach 👸🏼 Did we win Halloween?🥇👑🎃🏆,” Hilton jokingly captioned the post.

She also shared a closer look at their family race while on top of what appeared to be luggage-scooter hybrids. The mother of one wrote on top of the her TikTok video, “POV: you’re still kids at heart,” while showing a scene of her and Reum on their “carts,” moving side by side. Hilton had Prince Tokyo in her arms, while Reum held their son.

The pair drove in circles around a fountain covered in cobwebs in front of their home. Her dog could be seen sprinting after them in a few cute clips and even Phoenix got in on the fun, taking hold of the scooter handlebars just like his dad.

“Find someone who makes you feel like a kid again 🥹💕🎃,” Hilton wrote in her TikTok caption, alongside the hashtags “Princess Peach,” “Mario and Luigi” and “Halloween.”

Super Mario wasn’t the only costume theme for the family, as the DJ previously shared another adorable photo of Phoenix dressed up in an Elmo onesie.

“My lil Elmo. 🥹❤️👶🏼❤️,” Hilton captioned the shots, adding, “#BabysFirstHalloween 🎃.”

She also shared some pictures of Phoenix outfitted as a pilot to match Mom’s blue flight-attendant getup from Britney Spears’ 2003 “Toxic” music video. (Dad also got in on the fun and suited up as a flight-crew member, as well.)

In another look, Hilton drew inspiration from Katy Perry and rocked the singer’s famous mushroom ensemble. Baby Phoenix and his dad also matched that costume, dressing up as their own version of a mushroom.

“Usually I’m preparing my costumes, but I’ve already bought Phoenix probably 20 different costumes,” Hilton told PEOPLE last month leading up to Halloween. “He’s been my focus.”
