Move over, Scott Disick -- Kourtney Kardashian has model friends, too!
The 36-year-old reality star celebrated St. Patrick's Day with Miranda Kerr, Lily Aldridge and Michaeline DeJoria in Malibu, California, on Thursday, amid her ex-boyfriend's new romance with 20-year-old Christine Burke, a model who looks eerily similar to Kardashian's younger sister, Kendall Jenner.
During their girls' night out, the gal pals -- all dressed in black from head-to-toe -- snapped a number of selfies, showing off their pretty pouts and seemingly having a good time. Judging from the photos, the mom-of-three appeared to be in good spirits and unfazed by Disick's latest actions.
"I'll show you mine," Kardashian captioned a photo of her squad cuddling up close in the bathroom in order to fit into the frame.
"Reunited and it feels so good...," Kerr captioned a similar selfie.
Aldridge also took to Instagram to share a snap of their outing, simply writing, "Malibu Nights ❤"
Earlier in the day, Kardashian took her and Disick's youngest kids -- Penelope, 3, and Reign, 1 -- to lunch at the Beverly Hills Hotel, where they dined on bread, salad and veggies. The two are also parents to 6-year-old Mason.
As ET previously reported, Disick, 32, was photographed with Burke while the pair were out and about in Los Angeles on Wednesday. Despite the shock to fans, word of Disick's new relationship was apparently not a surprise to the Kardashian-Jenner clan.
"It's very new but Scott and Christine are dating," a source told ET. "The family has known about her before these pictures came out."
