A newly single Kourtney Kardashian went on a double date with Kris Jenner, her mother’s boyfriend Corey Gamble and her sister Khloé Kardashian at a California vineyard last week.

Kourtney, 36, joined Jenner, 59, Gamble, 34, and Khloé, 31, for a Malibu Wine Safari on Friday.

While lovebirds Jenner and Gamble – who began dating last fall – nestled together during the tour, the momager’s daughters took the back seat of the open wrangler.

Kourtney broke up with her off-and-on-again partner of nine years, Scott Disick, 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. (The stars have three children together: Mason, 5, Penelope, 3, and Reign, 6 months.)

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