Paris Hilton is ready for Sliv-mas!

The Paris in Love star, 42, showed off her impressive Christmas decorations — complete with a pink Christmas tree — in a TikTok video over the weekend ahead of celebrating the holiday season as a mom of two for the first time.

“Merry #Slivmas from #SlivingtonManor! 💕💕🎄💕💕 #SlivingMom ✨,” Hilton captioned the festive clip which was set to the tune of Michael Bublé’s “It’s Beginning to Look a Lot Like Christmas.”

The video began with Hilton opening the front door of her house to reveal a towering, lit Christmas tree decorated with white feathers and gold, glittery stars in her lobby as her pet dogs ran in front of her excitedly.

Hilton then showcased a pink Christmas featuring candy-shaped decorations as part of what appeared to be a celebration of the arrival of her newborn daughter, London Marilyn. Several pink balloons were also seen propped up spelling out “LONDON,” along with “Baby!” and “It’s a Girl!” alongside brightly-colored lights strung on the walls.

Boxes of pink and blue presents were also shown piled up by a table covered in plush toys.

On Sunday, the new mom of two posted a second video of the baby London bonding with older brother Phoenix Barron — who turns one next month — in a sweet moment as she sat on the floor with them in their nursery.

“Morning with my angels.🩵👶🏼👶🏼🩷 Phoenix is the best big brother!🥰” Hilton captioned. “So gentle & sweet with his baby sis.😇.”

In the clip, Phoenix sat in a baby bouncer beside Hilton as she cradled baby London.“Is that your sister?” she asked Phoenix as he stroked his sister’s head. “Go gently,” the mom of two told the 11-month-old. “Phoenix is a nice big brother. We love you, London!” she added.

Hilton recently spoke to PEOPLE about being “excited” for her first holiday as a family of four ahead of the premiere of the second season of her reality series, Paris In Love.

“My life just feels so complete, having my little baby boy and now my little girl,” she told PEOPLE. “I am so excited to have our first holidays together. Thanksgiving was so special, surprising everyone with London and getting to show Phoenix the Christmas tree for the first time. Seeing his eyes light up and seeing the wonder in his eyes, it’s such a magical experience. I can’t wait for our first Christmas together as a family.”
