Reality star Kourtney, 43, shunned a traditional bridal gown for a white minidress and veil, while the Blink-182 drummer, 46, opted for a black suit.
The intimate ceremony in Santa Barbara was attended by Kourtney’s grandmother and the musician’s father.
Photos shared on Instagram reveal the happy couple leaving in a convertible with a just married sign and a couple of tin cans tied to the back of it.
Another shows the newlyweds gazing adoringly at one another while sitting in the front seat of the vintage convertible.
“Till death do us part,” the mother-of-four captioned the intimate snaps.
There was no sign of Kourtney’s three children or her famous sisters at the low-key ceremony, but it is reported the lovebirds are planning to have a big wedding in Italy in the “near future”.
The nuptials come after Travis and Kourtney’s unofficial wedding at the Love Chapel in Nevada, which took place hours after the Grammy awards night in April.
