Paris Hilton and Carter Reum Celebrate Baby Son Phoenix's First Halloween with Adorable Family Costumes

It's baby's first Halloween!

On Monday, Paris Hilton and husband Carter Reum, both 42, celebrated Halloween for the first time with their little boy, son Phoenix Barron, 8 months.

The musician shared two wholesome posts to her Instagram page to celebrate spooky season with her little one, showing Phoenix look adorable in photos from the holiday as he dressed up to match with his mom's previously revealed Halloween looks.

For Phoenix's first fit, he dressed as a pilot to match his mom — who wore the iconic outfit from Britney Spears' 2003 "Toxic" music video. Hilton's teal Pan Am costume and silver boots were already a hit, but next to her son's aviator sunglasses, mini pilot's uniform, and black Nikes, she really pulled off the look. As previously reported, Hilton wore her look to the Casamigos Halloween party over the weekend.

Reum also posed next to the duo for a bigger family pic, as he also went as a pilot to match the theme. "Ladies and gentlemen, let me introduce you to your flight crew. ✈️ 👱🏼‍♀️👶🏼🧑🏻‍💼💕," Hilton captioned the post.

In an earlier post, Hilton channeled yet another pop star and dressed up as Katy Perry — giving fans a closer look at her Las Vegas residency-inspired mushroom fit that she wore to Vas Morgan and Michael Braun's Halloween Party on Saturday night.

The look, which consisted of a red outfit and mushroom-top hat, was backed up by her 8-month-old, who went as a mushroom himself in a tiny beige onesie.

In images from their photoshoot, Hilton and Phoenix could be seen smiling as they again posed with Reum, who also wore the mushroom hat and a red top for good measure.

"A full family concert✨🍄✨ @KatyPerry," Hilton wrote.

Earlier this month, Hilton opened up to PEOPLE about life since welcoming baby Phoenix in January, sharing that her son has "changed my life in every way."

"Phoenix is just my world. He is the most beautiful little baby boy," Hilton said. "He's growing up so fast, but he has just made my life feel so complete."

"I just feel like the luckiest girl in the world every single day for this beautiful family that I have," she continued.

As for the most surprising part of motherhood, Hilton added, "It's just how much love I could have for someone. 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 and Reum quietly welcomed their first child together on Jan. 16, 2023, via surrogate.

The pair, who married in late 2021, kept the news of their baby boy to themselves for over a week.

Hilton later announced Phoenix's arrival eight days after his birth on Instagram with a close-up photo of her holding his hand, writing, "You are already loved beyond words 💙."
