Khloe Flaunts Curves at Kourtney Kardashian's Baby Shower -- Which Sister Was Missing?!

Kourtney Kardashian celebrated her impending bundle of joy at a "Breakfast at Tiffany's"-themed brunch on Wednesday at the Montage Hotel & Resorts in Beverly Hills with her family by her side.

The expecting star took to Instagram to share a sweet snapshot with her famous siblings, writing, "Baby shower brunch! #breakfastAtTiffanys."

Kourt flaunted her baby bump in a black silk tuxedo-style dress with oxford flats.

Meanwhile, Kim Kardashian covered up in a black leggings and a matching blazer. This sophisticated look is much more modest than her naked Paper magazine cover, which was intended to "break the internet" earlier that day.

Kim's 1-year-old daughter, North West, wore a tiny white blazer and denim mini skirt for the fancy soiree.

Kylie Jenner paired her bright green 'do with a chic white top and black leather pants, while Khloe Kardashian stole the show in a tight white crop top and matching pencil skirt.

It's hard to hide all that booty in this outfit -- is someone trying to upstage Kim?!

Kendall Jenner was MIA from the festivities, but appeared to be missed by her sisters.

Khloe shared the pic above, writing, "We miss you our little croissant @kendalljenner."

Kourtney is currently expecting her third child with boyfriend Scott Disick. The two are already the proud parents of son Mason and daughter Penelope. We can't wait to see the little one!
