Kourtney Kardashian was surrounded by the most important people in her life – her family – as she was celebrated with a baby shower in L.A. over the weekend.
The afternoon fete, which also included a large circle of friends, was attended more than 50 guests who ate at tables set outside around the pool in the backyard of Jenner’s Hidden Hills home. Attendees were all asked to dress in the theme of “The Hamptons” for the shower, a source tells PEOPLE.
