It's another girls-day-out for the Kardashian-Jenner family, as the pregnant 'Keeping Up With The Kardashian' star Kourtney Kardashian was the guest of honor in a baby shower held last November 12 at the Conservatory at the Montage Hotel in Beverly Hills, California.

Kourtney, Khloe, and Kim Kardashian were photographed arriving at the venue wearing their monochrome-colored outfits to attend to the very classy 'Breakfast at Tiffany's' themed party for the third time mom-to-be, Kourtney.

"The baby shower was held in a private room on the penthouse. It was buffet style with lots of pastries and the usual breakfast items. There were about 12 young ladies including Kim, Khloe, and the youngest sister [Kylie]," a source told Hollywood Life.

The theme did not directly point to the gender of Kourtney's baby and all the guests including Kourtney's family and friends were wearing natural-colored outfits. Reports speculate that it's a way to hide the gender of the baby to the press.

The Kardashian-Jenner sisters shared some sneak peak photos of the exciting event. Kourtney posted a photo of her with Kim, Khloe, and Kylie Jenner on the table filled with white flowers and Tiffany blue-colored boxes. She captioned the photo with "Baby shower brunch! #breakfastAtTiffanys."

It looked like a great brunch as Khloe posted a sneak peak photo on Instagram showing a large croissant which she purposely took for Kendall Jenner who's absent at the party. "We miss you our little croissant @kendalljenner." Khloe wrote.

Khloe also posted a photo of her and their long-time family friends, sisters Malika and Khadijah Haqq. She captioned the photo with "Besties who brunch".

"The ladies seemed to have a great time celebrating Kourtney's baby. They were laughing and enjoying themselves," an onlooker told People.

The 35-year-old mother of two hasn't officially announced her due date, but reports speculate that it will be soon. Kourtney's pregnancy journey for her third child has been showcased on her newest reality show with Khloe called 'Kourtney and Khloe Take the Hamptons' which is currently being aired.
