Nicky Hilton celebrates her youngest daughter Teddy’s 6th birthday at Radio City Christmas Spectacular with brother Barron Hilton II and his family

Nicky Hilton attended the Radio City Christmas Spectacular annual musical holiday show celebrating her youngest daughter Teddy's sixth birthday in New York City on Wednesday.

The socialite, 40, brought her two of her three children and was accompanied by her brother, Barron Hilton II, 34, in addition to his pregnant wife, Tessa Gräfin von Walderdorff, 29, and their own children.

Nicky's husband, James Rothschild, 38, and their son — whose name and face have yet to be revealed since they welcomed their third child in early 2022 — were not seen in photos and did not appear to be present.

The fashion designer — who attended the Max Mara pop-up event in Aspen with her mother, Kathy Hilton, a few days earlier — looked dazzling in a black turtleneck and a glittering silver skirt.

To match the rest of her look, she wore a pair of slingback kitten heels covered in silver glitter and complete with black suede toecaps.

She let her honey blonde locks loose in a straight hairstyle with a black headband adorned with sparkling rhinestones.

For the family celebration, she opted for a pink and dewy makeup look with a copper smokey eye, baby pink blush and a glossy nude lip.

For an overall cohesive look, she also wore a manicure with glossy black polish.

At one point, Nicky posed for a photo with the entire family and held the birthday girl on her lap.

Her daughters Lily-Grace, seven, and Teddy, now six, wore matching black pinafore dresses over white collared Peter Pan blouses.

Nicky's eldest child wore green leggings under her dress and wore a lavender fleece jacket.

Like her mother and younger sister, she also let her hair down and dressed up with a headband.

Teddy – born on December 20, 2017 – wore black boots and a chunky cream headband.

The proud parents announced in September that they are currently expecting their third child together.
