Kylie Jenner brings daughter, Stormi, 4, as her plus-one as she welcomes 2023 with sister Kendall, Justin Bieber and wife Hailey at a party in Aspen

Young Stormi Webster got to spend part of her New Year's Eve hanging out with her mother and her famous friends as they rang in 2023 in Aspen. 

The four-year-old was Kylie Jenner's plus-one to the glamorous celebration that included her aunt Kendall, Justin and Hailey Bieber, best friend Stassie Karanikolaou and many others.

The adorable tyke was warmly dressed in a cream and black wool coat and black boots as she arrived at the celebration with Kylie, 25, and Stassie, 25. 

The Kylie Cosmetics founder showcased her toned legs in a sheer eyelet patterned unitard and high heels while covering up in a black fur jacket. 

The reality star slicked her hair back into a pony tail and walked into the restaurant wearing a pair of black wraparound sunglasses and highlighting the look with a bold red lip. 

Stassie stepped out of the SUV in a dark gray satin halter gown which plunged down to her naval. 

The YouTube star accessorized the frock with crystal and white gold necklaces and matching belt. 

Her long, dark locks were styled in a flirty updo with tendrils framing her face. 

Inside the party, the influencer sipped from a beverage as she flirted with the camera during the friends' sit-down dinner.

Kendall Jenner, 27, arrived in a waterproof orange and black coat with a tiger stripe design. 

The Kardashians star carried a simple black handbag.

Her long hair was styled straight and underneath she was dressed in a body hugging black turtleneck leotard and high heels. 

The 818 Tequila maker accessorized the look with a pair of large gold hoop earrings. 

Justin and Hailey Bieber both donned all black to welcome in 2023.

The Grammy winner, 28, chose a casual approach to the festivities, arriving in a pair of black pants, a charcoal hoodie and a white billed cap and sneakers.

Hailey, 26, displayed her toned abs and legs in a strappy mini-dress with a cutout at the torso, black stocking and high heel boots.

The Rhode Skincare founder styled her dark blonde hair in a French twist with one tendril in front. 

She accessorized the look with a small black purse and large gold and diamond earrings. 

The model not only exposed her toned midriff in the look but her back as well, as the frock featured a mock thong design.

Capital Records executive Carter Gregory, 29, was in the group, looking handsome in a black pinstripe suite with leather lapels and a black turtleneck sweater. 

Kylie shared many snaps from the evening with her famous friends on Instagram.

Engaging her 376 million followers on the photo-sharing platform, she simply wrote in a caption: 'NYE.'

Taking to her Stories, she shared the spotlight with her loved ones, posting clips of Kendall, Hailey, and Stassi separately.

Kendall was less active on social media throughout the festive evening, but she did pop in to post in her Instagram Stories. 

Hailey welcomed in the new year applying Rhode Peptide Lip Treatment and wearing a Happy New Year hat as she grooved to the beats of Lionel Richie's classic hit All Night Long.
