Hey-o, Jackie O!

Kim Kardashian took to Instagram Tuesday to post a series of photos from a 2017 Steven Klein Jackie O photoshoot to wish her and Kanye West’s eldest child a happy birthday.

North West, who turned 8 years old Tuesday, posed with mom Kim, 40, in a few behind-the-scenes images from the pair’s First Lady-themed shoot for Interview magazine in 2017.

Kim looked like a stylish replica of Jackie Kennedy in a powder-blue suit with black bows and her dark hair in an updo. North matched mom in a coat the same shade of blue with her hair up in two mini-buns.

“North, one day you will see these messages all printed out for you in the books I am making for you and so hope you feel the love because you bring so much love and joy into all of our lives!” Kim captioned the post.

“You are the silliest, most stylish, most creative person who knows exactly what they want in life! I’ve never met anyone like you! I picked these BTS to post of North and I from this Steven Klein Jackie O shoot bc it just reminded me of the bond North and I share and he always captures the emotion so well!”

North first made her debut on “Keeping up With the Kardashians,” filming sequences for West’s “Only One” music video in 2015. North has also made appearances at West’s Yeezy shows in the past.

Other celebrities, including Emily Ratajkowski, were quick to comment with their own well-wishes for the child star.

Kardashian and West also share daughter Chicago, 3, and sons Saint, 5, and Psalm, 2. Kardashian said in February she “totally trusts him” with their kids amid divorce rumors that proved to be true.

Kris Jenner also took to Instagram to wish her granddaughter a happy birthday as she posted several never-before-seen images of the family. One included West hoisting North above his shoulders while the father and daughter shared a laugh.

“Happy birthday to our beautiful Northie!!!,” Jenner said. “You are truly such a ray of sunshine and you light up every room with your amazing smile and huge heart.”
