Kim Kardashian shows off her curves in a fitted outfit as daughter North West sports custom pajamas while celebrating her 11th birthday in NYC

Kim Kardashian showcased her curves as she stepped out with daughter North West and a group of her close pals to celebrate her 11th birthday in NYC on Saturday.

The SKIMS founder, 43 – who recently turned heads while grabbing a smoothie in Calabasas – was seen joining her eldest daughter and her friends as they stopped by Paint Me Bear, an art studio located in the heart of Manhattan.

The mother-of-four donned a short-sleeved, light gray shirt as well as a fitted, dark gray tank top.

She additionally slipped into a pair of sculpted, gray leggings and a pair of open-toed pumps to complete the look.

Her platinum locks were parted in the middle, and effortlessly flowed down past her shoulders in light waves. 

Kim opted for minimal accessories for the daytime festivities, and added a pair of stylish, gray-rimmed shades. 

The TV personality easily carried a fuzzy, cream-colored purse over her left shoulder to hold a few items she needed during the busy day. 

Her daughter – who officially turned 11 on Saturday – held an excited smile on her face as she strolled closely behind her mother to head to their next destination after a visit to Paint Me Bear. 

North and her friends all sported pink ‘I [heart] NY’ pajama bottoms as well as matching, black shirts that had, ‘North’s 11th birthday party’ printed on the front. 

Kim was also joined by a few close pals of her own, including La La Anthony and media personality Kai Cenat during the birthday celebration. 

At one point, they were spotted stepping back onto a party bus as the bright, summer sun shone down.  

According to Page Six, The Kardashians star whisked herself, North and a group of her friends to the Big Apple in her private jet on Friday. 

Upon arriving to the city, they made a stop at the popular eatery, Serendipity3, located on the Upper East Side and indulged in scrumptious treats, such as ice cream sundaes and frozen hot chocolate. 

The group also sported different, matching pajamas that had ‘I [heart] NW’ on the front – mimicking the iconic ‘I [heart] NY’ shirts. 

Last year for North’s birthday, Kim notably threw a lavish sleepover for her daughter and pals at the Beverly Hills Hotel. 

Also on Saturday, Kim penned a sweet birthday tribute to her eldest daughter which was uploaded to her main Instagram page, along with an assortment of throwback images. 

The star shares North, as well as Saint, eight, Chicago, six, and Psalm, four, with ex-husband Kanye West. 

In one snap, the mother daughter duo struck a quick pose for a selfie as Kim puckered her lips towards the camera, and her daughter flashed peace signs with her hands. 

Another picture showed North falling asleep on Kim’s chest while another captured the pair pausing for another selfie while seated inside a vehicle with an adorable pup between them. 

While the reality star donned a cheetah-print ensemble, she held a big smile while embracing her daughter in one image. 

Another snap was taken as the two wore similar, all-black ensembles and chunky necklaces while sitting on a concrete step. 

Kim also included a short clip as North excitedly repeated ‘I’m in the video!’ as the star filmed inside a car. 

In the caption of the post, the TV personality wrote, ‘Thank God for you ✨ Happy 11th birthday my sweet girl North. I love you so so so much.’ 

Social media users jumped to the comment section to also send birthday wishes to North, including Kourtney Kardashian’s husband, Travis Barker, who penned, ‘Happy Birthday North.’ 

La La Anthony added, ‘Happy Birthday Northie!! I love u so much bestie ❤️❤️❤️having the best time today!!!!’ 

Model Winnie Harlow typed out, ‘Happy birthday cutie ❤️❤️❤️,’ while Khloe Kardashian wrote, ‘Happy birthday Northie ❤️❤️❤️.’ 

Kris Jenner shared, ‘Happy birthday my beautiful Granddaughter I love and adore you!!!!!’ followed by various emojis. 

She also penned her own birthday tribute to North on her main Instagram page on Saturday for her ‘one-of-a-kind’ granddaughter. The self-proclaimed ‘momager’ shared a carousel of throwback photos of North to honor the pre-teen’s big day. 

‘Happy birthday to my beautiful granddaughter, North!’ she wrote behind a photo of the Los Angeles native wearing a Simba costume from her recent The Lion King performance.

‘Watching you grow into the amazing, talented, creative young girl you are has been one of the greatest joys of my life,’ she penned.

The sweet note was behind a family photo of Jenner, Kardashian, North and a friend of the youngster.

‘Your confidence is inspiring and it always amazes me how much energy, excitement and love you put into everything you do!!’ she wrote behind a snap of two sharing a sweet moment while holding hands.

‘Whether it’s your singing, dancing, writing, amazing music producing, your love for fashion, everything you do you put your all into it,’ she penned behind a snap of herself, the birthday girl and Kim.

The 68-year-old even commended the birthday girl for her acting debut, which initially received mixed reviews.

‘You are truly spectacular and one of a kind. I’m so proud of your Lion King performance at the Hollywood Bowl. You are superstar, Northie,’ the doting grandmother expressed.

‘I just can’t believe how fast you’re growing up and how creative you are you’re reaching for the stars and following your dreams,’ she added behind a snap of the youngster behind the Notre-Dame Cathedral in Paris.

‘Never stop dreaming big and shining bright. I love you soooo much! Love, Lovey,’ she finished. 

The message was penned over a silly image of North carrying her famous mom Kim on her back.

Kim later took to her Instagram stories to share a few videos as she flaunted her look for the day while grabbing a bite to eat inside what appeared to be a pizza restaurant. 

She struck a variety of poses to also showcase her glammed up look with La La Anthony soon joining in on the fun. 

The BFFs flashed cheerful smiles on their faces as they continued to pose together during the big celebration. 

Kim later posted a snap as she paused for a picture with both Anthony as well as Kai Cenat.
