Kim Kardashian pulled out all the stops for her daughter North's 11th birthday, treating her and her friends to a day out in New York City. Joined by LaLa Anthony, Kim sported a sporty mom look while the birthday crew enjoyed the concrete jungle. North rocked a commemorative t-shirt and pink "I Heart NY" pajama pants, with all attendees in matching outfits. YouTuber Kai Cenat even made an appearance during the fun-filled day. The group ended up at an art studio in SoHo to paint decorative bears, a unique 11th birthday activity. This comes after Kim's extravagant birthday parties for her kids, including a pink-themed party for North's 10th birthday. Although Kanye West was not in attendance in NYC, the close relationship between him and North ensures they will celebrate together when she returns to LA.
