Happy birthday, Saint West!

Kim Kardashian West and Kanye West‘s son turns 1 on Monday, and as usual, the birthday wishes are already rolling in from the famous family.

Khloé Kardashian and Kendall Jenner were the first to wish the little star a happy birthday, each taking to their websites and apps to send a sweet shoutout.

“I can’t believe how quickly time flies!” gushed Khloé, 32. “Watching my little Saint grow this past year has been amazing.”

“He’s seriously such an angel and could not be more adorable,” she added. “What a light he’s been for our family!”

Kendall, 21, took a moment to reflect on how special her nephew is to her and the rest of the KarJenner crew.

“Saint, I can’t believe it’s been a year since you came into our lives!” she wrote. “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!”

Kris Jenner, meanwhile, celebrated her grandson’s big day on Instagram.

“Happy birthday to our sweet angel, Saint!” Kris, 61, captioned the picture. “#family #love#happybirthdaysaint #saintwest.”

Saint’s oldest auntie, Kourtney, 37, also shared a heartfelt post via Instagram, writing, “I can’t believe this was one year ago today. Happy birthday my little Sainty.”

And while Kim, 36, has refrained from posting on her app in the two months since her traumatic gunpoint robbery in Paris, the Keeping Up with the Kardashians star’s best friend Jonathan Cheban, who is taking over content this week, shared a birthday message of his own — and two new pictures of the birthday boy cuddling with Mom.

“I can’t believe today is Saint’s first birthday!” wrote Cheban, 42. “One thing people may not know about me is that I’m obsessed with babies, LOL. In honor of his birthday, I convinced Kim to let me share some never-before-seen pics! Happy birthday, Saint!”
