She was seen dancing in the background while Alabama and Landon were having some fun and filming a TikTok video together.
The adorable clip, which had made fans go mad with excitement, features the reality star bopping her head in the background while holding a mug and sipping a drink out of it as the kids dance to the tune of the hit song "Shower" by Becky G.
The mother of three herself donned in a casual look with a baggy black t-shirt and skinny jeans and wore her bob hair cut in a ponytail.
The pair's relationship is proven to be going strong. Last month, Kourtney helped her newfound love, the 45-year-old Blink-182 drummer, conquer his fear of flying.
As previously reported, Travis has had a fear of flying due to his involvement in the deadly plane crash that nearly killed him in 2008, which prompted him to stop flying altogether. He had since only traveled via land or boat to destinations, including any of his tours.
The flight was his first in 13 years since he suffered the tragedy that had left him "covered in jet fuel and engulfed in flames."
An insider revealed, "It's a huge deal that Travis flew to Cabo. The plane crash many years ago was extremely traumatizing. He has needed a lot of help to get to this point."
The Poosh founder has reportedly been understanding of her man's past trauma and "never pushed for him to fly."
"Kourtney has been very supportive," they went on. "They have managed to travel in the US without having to fly, and Kourtney has been totally fine with it," the source continued.
Adding more evidence of their concrete love for one another, Travis recently opened up in an interview claiming he feels "invincible" when Kourtney is around him.
