The couple, who tied the knot in May, are now sharing some never-before-seen photos from the celebration.
In honor of Kourtney's grandmother's birthday, the reality star revealed photos from the couple's courthouse wedding in Santa Barbara.
The private ceremony went down just a few days before the couple's stunning Italian wedding and was only attended by two people — Travis' dad, Randy, and MJ.
"My special, sweet, chic, sophisticated, smart and most wonderful grandmother. Happy birthday my MJ," Kourtney captioned a photo of the duo toasting the wedding at a post-ceremony luncheon.
She continued, "So happy you could be one of the only two guests we had when we were legally married, I will always remember this day and night with you."
Kourt also shared photos of the foursome posing outside of the courthouse, where Kourtney could be seen wearing a bridal mini dress and veil.
In the final snap shared, Kourtney and Travis signed their marriage certificate — making things official before they jetted off to Italy.
It looks like it was a truly special day for the couple and two of the most important people in their lives! You can see all of the new photos here.
