Kim Kardashian shares rare photos of Saint West to celebrate his first birthday

While the rest of the Kardashian and Jenner clan took to social media to post messages, the mother of two gave best friend Jonathan Cheban permission to publish photos of Saint on her website and app.

Cheban took candid photos of Saint trying to grab Kardashian's face and wrote a gushing note to the one-year-old.

"I can't believe today is Saint's first birthday! One thing people may not know about me is that I'm obsessed with babies, LOL," he said. "In honour of his birthday, I convinced Kim to let me share some never-before-seen pics! Happy birthday, Saint!"

Given her social-media hiatus following the Paris robbery and recent hospitalisation of husband Kanye West, Kardashian's friends and stylists have kept her app and website active with posts for fans who pay for access each month. The reality star was also featured in a photo shoot alongside her sister, Khloe.

Khloe Kardashian also dedicated a post on her website to the birthday boy. "I can't believe how quickly time flies!" she wrote. "Watching my little Saint grow this past year has been amazing. He's seriously such an angel and could not be more adorable. What a light he's been for our family!"

After walking in the Victoria's Secret Show in Paris last week, Kendall Jenner took the time to also write on her site, "Saint, I can't believe it's been a year since you came into our lives! You're the sweetest addition to the fam. Even though you're still so young, you already have the most happy and amazing personality. I love you!"

Meanwhile, Kourtney Kardashian took to Instagram to share a selfie with her nephew on the day he was born. "I can't believe this was one year ago today. Happy birthday my little Sainty," she captioned the photo.

The family held a first birthday celebration with hundreds of blue balloons. Saint is the second child of the couple dubbed Kimye, and was born at Cedars-Sinai in LA on December 5, 2015.
