Baby by Instagram? Kourtney Kardashian celebrated her third pregnancy in style Wednesday with a themed brunch and a whole lot of social media.

With most of her family by her side, the eldest Kardashian sister held a "Breakfast at Tiffany's"-themed brunch at the posh Montage Hotel & Resorts in Beverly Hills, Calif. As they often do, the "Keeping Up With the Kardashians" stars gave their social media followers a glimpse into the baby shower.

"Baby shower brunch! #breakfastAtTiffanys," Kourtney captioned a photo with her siblings where she, like sister Kim Kardashian, donned black. Sisters Khloe Kardashian and Kylie Jenner went the opposite direction, wearing white.

It was a friends and family affair! Khloe posed with BFF Malika Haqq and her twin sister Khadijah Haqq on the deck of the hotel, captioning the photo, "Besties who brunch." A turquoise-haired Kylie got in on the Instagram action too, posting a photo with family friend Joyce Bonelli with the caption "breakfast @ tiffanys."

Absent, though, was aspiring model Kendall Jenner -- but she wasn't far from their thoughts.

At one point Khloe Instagramed a photo of a single croissant, writing, "We miss you our little croissant @kendalljenner."
