The three spent time together in the Hamptons in New York, where Kourtney Kardashian has been staying with her family while filming a spinoff of the family's reality show, Keeping Up With The Kardashians with fellow sister Khloe Kardashian. Jenner, 58, posted a photo of herself with Kim, 33; Couric, 57; supermodel Christie Brinkley, 60; and another friend on Instagram late on Saturday, July 5.
While Couric did not post anything on social media from the event, Brinkley, who also lives in the Hamptons, and Kim shared several photos of themselves posing for selfies. They were also joined by actress Marlo Thomas of the 1960s sitcom That Girl.
"With Two Icons .. That Girl, Marlo Thomas and that other girl who needs no introduction..@kimkardashian!" Brinkley said. "Both were so sweet and charming! Proud Mom Kim showed me baby pictures of her most gorgeous baby, North. And Marlo will be appearing in Clever Little Lies at @guildhall as of the 19 July for 3 weeks...( a must see!)"
"I think Kim is an undeniable Icon of Beauty...and having met her last night for the first time I can only say she was sweet as could be, a proud Mom like many of us who had the same glow we all do when we share a picture if our kids," she added. "And her mom who was also there also has that glow as she watched her daughter move around the party. They shared what seemed to be a close and loving relationship."
At the event, Kim wore a flowy, white shirt and black pants, while Brinkley donned a black mini dress. The two posed for selfies.
