Paris Hilton threw a spectacular sea-themed birthday party to celebrate her son Phoenix turning one, joining by a number of celebrity guests including Kelly Osbourne

Paris Hilton went all out to celebrate her son Phoenix’s first birthday, throwing a lavish underwater-themed bash at her home.

The reality star, joined by guests including Lance Bass, Kelly Osbourne, and Rumer Willis, transformed her backyard into an underwater wonderland. A whimsical arch adorned with red, blue, and orange balloons shaped like fishes set the scene, along with music from Disney’s The Little Mermaid playing in the background.

Paris, 42, wore a long blue dress fit for a princess, a crown, and carried a large quilted Chanel bag, while Phoenix donned a white t-shirt, khaki pants, and a stylish newsboy cap.

To make the celebration even more special, Paris arranged a petting zoo for the party guests with rabbits, baby goats, chickens, and sheep. She even brought a ‘unicorn’ to entertain the little ones and the partygoers. The youngest member of the Hilton family, London Marilyn, two months old, also attended the festivities.

On Friday’s episode of The Jennifer Hudson Show, Paris had teased she had “big plans” to celebrate her first born’s birthday with a petting zoo, “ball pit and slides.”

“I know he’s only one but all the parents are coming and there will be some older kids as well,” she explained. “It will be fun for all ages over at the house. It’s going to be really sweet.”

Paris, known for her social media presence and reality TV fame, has been sharing glimpses of her family life, and Phoenix’s journey during his first year, on Instagram.

In a recent post, she expressed gratitude for the joy Phoenix brought to their lives and celebrated his first birthday. Paris’ post showcased the bond between her and her son, capturing precious moments from their private jet travels to Phoenix’s various adorable costumes and playtime adventures.

She wrote in the caption: “One year ago, a beautiful angel baby entered our lives, bringing so much love and happiness,

“My precious little one, you are more than a dream come true. You make my life complete. “Every day with you is a priceless gift, and I’m endlessly grateful to be your mommy,” the star went on, continuing to gush over her little boy.

“Celebrating your first of many birthdays, Baby P – here’s to a lifetime of laughter, love, and wonderful adventures with our cutesie crew!

“Happy 1st Birthday!” Paris added.

Paris, who is married to Carter Reum, welcomed Phoenix in January 2023, and London in November 2023 via surrogates, after Paris confessed that she chose to take that route because her life has been “so public”.

She kept Phoenix a complete secret from her family and the rest of the world until he was born, and with London, only her mother and sister knew that the surrogate was pregnant.
