Kim Kardashian shared this sweet photo of her husband Kanye West and their daughter North West
"This is what life is about!" she wrote next to the photo. "Our baby girl turned 1 today! We played so hard they passed out while we were watching the game! Happy Father’s Day to the best daddy in the world!
"The way you love our daughter and protect her makes me filled with so much love! #BestDayEver #Twins #HappyFathersDay #HappyBirthday."
Grandmother Kris Jenner also shared a touching message to North. "Happy 1 Birthday to my beautiful granddaughter North!!!" the Kardashian matriarch wrote alongside a photo of the one-year-old. "You are an angel and I love you so very much!!! #lovebug #pinchthosecheeks."
The trio had a day out in Manhatten to celebrate North's birthday and Father's Day
Kim and Kanye marked Nori's big day – as well as Kanye's second Father’s Day – with a visit to the Children's Museum of Manhattan.
The trio were spotted walking inside the attraction, Kim, 33, carrying the birthday girl while showing off her curves in a tight pencil skirt and white vest top.
North West's new diamond earrings
Also on display was North's new accessories – diamond earrings. The studs are a new addition for the tot; they weren’t seen in the photos for Kim and Kanye’s wedding last month, and were perhaps a birthday present from her parents.
