As documented in a Instagram post from Kardashian, the pair apparently enjoyed dinner together before going to a pop-up theater set up in the sand, surrounded by dozens of lit candles.
There the newly engaged couple watched the Christmas classic Home alone before Barker set off fireworks nearby. In a video from her post, Kardashian and the musician can be seen holding each other close as they gaze at the night sky.
On his Instagram story, Barker shared Kardashian’s post and also shared a video set off the fireworks.
“Best night ever,” he captioned the short clip. “I love you forever @kourtneykardash.”
Kardashian and Barker have concerned in October after dating for almost a year. The reality star said ‘yes’ after a lavish proposal on the beach in Montecito, California, with a multitude of roses and candles.
Earlier this month, the couple attended family friend Simon Huck’s wedding and teased their own impending wedding.
At the time, Kardashian shared a sweet series of photos of the festivities where she and Barker held hands and laughed.
“Go to the chapel,” she captioned the post, tagging Huck and his groom Phil Riportella before adding a champagne glass emoji. Barker then commented, “Our next turn,” with a red rose emoji.

AN source told PEOPLE last month that while the engagement is still fresh, it’s only a matter of time before the founder of Poosh and Barker come down the aisle.
“The question was never if they would get engaged, it was more when,” the source said. “Travis just adores Kourtney. He treats her like a princess and is a great guy.”
