Inside Paris Hilton’s lavish bash for her son’s first birthday

She’s the queen of the party seen so it’s no surprise then that Paris Hilton pulled out all the stops for her son Phoenix’s first birthday.

Paris (42) transformed her Beverly Hills backyard for a Sliving Under the Sea-themed party, with decor to transport guests to a magical undersea world (if you're wondering, "sliving" is a word Paris herself cooked up – a portmanteau of "slaying" and "living").

In party videos posted on her TikTok account, the heiress and DJ showed off the star-studded bash, which was attended by, among others, Kelly Osbourne, Rumer Willis and Jessica Hart.

“I’ve thrown amazing birthday parties my whole life,” she says in a clip as music from Disney's The Little Mermaid plays in the background.

“So, to now be able to do this for my little boy is such a special memory.”

In another video posted on Instagram, Paris and Phoenix are seen in a petting zoo with rabbits, goats and lambs.

Paris's husband, Carter Reum (42) and their two-month-old daughter, London, were also seen enjoying themselves at the party.

The mom-of-two has said she's loving motherhood.

"I just feel so at peace, just so happy and so grateful for my husband and this beautiful family and life that we're building together, and I couldn't imagine anything else."

Paris and Carter's children were conceived via surrogate, something Paris deliberately kept private.

“I just feel like my life has been so public and I just wanted something for me. I didn’t want the media and people online just speaking about my son even before he was here on this earth."

Now she’s happy to share glimpses of her pigeon pair with the world.
