Kris Jenner and boyfriend Corey Gamble went on a romantic Malibu Wine Safari on Friday. Kourtney and Khloe Kardashian joined the couple at a California vineyard.

While Jenner and Gamble snuggled together during the tour, the momager's daughters took the back seat of the open wrangler.

Kris and Corey giggled and chatted the whole trip, sharing bags of popcorn and showing each other images on their phones.

While Kourtney and Khloe were keen on wearing their seatbelts, the two lovebirds were too distracted by each other and forgot to buckle theirs.

Jenner and 33-year-old Gamble started dating in October 2014, a year after she and Bruce called it quits on their 22-year marriage in October 2013.

"We ended a marriage, but that's not the end of our friendship," Jenner told Us Weekly at the time of their split. "I will always love him, but we are no longer a couple in that way."

Khloe took to her Instagram to share a snap of hee and Kourtney with a giraffe and captioned it, "Say cheese!!!!"

There was no sign of Khloe's rumored beau James Harden after being spotted in each other's company several times.

As expected, Scott Disick was not invited to their fun getaway. Kourtney broke up with her off-and-on-again partner of nine years last week after he was photographed partying hard and spending time with another woman.

"Scott insisted that his drinking is under control, that he's not in a spiral, but everyone around him knows the truth," a source told PEOPLE last week. "He has been lying to everyone, saying that he's clean and sober and he insists that he doesn't have a problem."

An insider also said Disick, 32, felt "overwhelmed" after the birth of his new baby boy.

"Scott rebels against the crazy responsibility of having three kids," the source explained. "He acts out, he drinks too much and he embarrasses Kourtney."
