Passersby who were lucky to get a glimpse of the nuptials said Kourtney's grandmother MJ was standing by her side.
Kourtney donned a veil and white wedding gown that was cut short at the knees, while Travis wore a sleek black tuxedo.
The Poosh founder and the Blink-182 drummer were photographed driving off in classic black lowrider convertible, which had a sign strapped to the front that read "Just Married".
Kourtney and Travis' wedding comes just days after they hosted what appeared to be a wedding shower in Palm Springs, California.
Last Wednesday, attendees posted photos on social media of a “Kravis 4 Ever” balloon display.
The happy couple's legitimate wedding comes a month after they got "hitched" in a small Vegas ceremony following a night out at The Grammy Awards.
While no papers were signed, the pair looked like they had the best of fun tying the knot.
“Once upon a time in a land far, far away (Las Vegas) at 2am, after an epic night and a little tequila, a queen and her handsome king ventured out to the only open chapel with an Elvis and got married (with no license). Practice makes perfect,” Kourtney wrote on Instagram alongside snaps from the evening.
Kourtney and Travis were first linked in October 2017, when his daughter, Alabama Luella Barker, revealed she’d spent some time hanging out with the Kardashian clan, when she would have been about 11 years old.
Given how close they lived to each other, it was barely major news when the pair were spotted grabbing dinner and heading to church together in 2018, and then again, the following year.
It wasn’t until 2021 that things really started kicking off for the mutually obsessed pair.
Rumours were sparked when Travis began leaving some flirty comments on pictures posted to Kourtney’s Instagram page.
Eagle-eyed fans soon noticed they’d both posted pictures taken at Kris Kardashian’s Palm Springs home, but it wasn’t much longer until they made it official, with Kourtney posting a pic of her hand holding Travis’s recognisably tattooed hand.
And from then, it was on for the pair, who began to post one PDA-packed pic after the other throughout 2021.
In April, Travis shared a few snaps of the pair smooching, as well as a video of Kourtney sucking his thumb, all in honour of her birthday.
The romance continued with plenty of intense, public kissing, gifts shared, and another iconic moment where Kourtney gave Travis a tattoo.
However, no one was quite ready when the pair suddenly announced their engagement in October 2021, after what seemed to be less than a year of dating.
Travis led Kourtney to a seaside spot, where thousands of roses had been set up in a heart shape.
He popped the question, presenting her with a stunning diamond ring. The pair documented the moment in snaps later shared to their Instagram pages.
