Keeping Up With The Kardashians star Kim, 33, threw a child-friendly Coachella-themed bash for North over the weekend, dubbed Kidchella.
In the image she uploaded to Instagram today, she can be seen holding baby North while Kanye smiles over her shoulder. They are standing in front of an elaborate, multi-coloured cake.
Kim added the caption: "Our baby girl's first birthday party #kidchella."
Kim's mum Kris Jenner and grandmother Mary can be seen in the background snapping pictures of the special moment.
Although it was North's big day, this is actually the first picture of her at the event we've seen. Despite living her life in front of the cameras, Kim only rarely shares photos of her little girl online.
North was born on 15 June 2013 at Cedars-Sinai Hospital in Los Angeles.
Kanye jetted back to Los Angeles at the weekend just in time for her daughter's birthday celebrations. Last night, he whisked new wife Kim out to dinner in Hollywood.
The couple were seen leaving Craig's restaurant in Kanye's incredible sports car. We. Are. So. Jealous!
They married in a lavish fairytale ceremony on 24 May in Florence, Italy after a week of wedding parties in Paris. They immediately honeymooned in Ireland, before jetting to Prague for a friend's wedding.
Kimye enjoyed a second honeymoon to Mexico earlier this month.
