Inside Kim Kardashian's Camp-Inspired Baby Shower

— -- Guests may have come dressed in their pajamas, but the camp-inspired baby shower to celebrate Kim Kardashian's second child was anything but casual.

Snaps from inside Sunday's indoor glamping affair show guests wearing coordinated periwinkle and pale pink striped pajamas and sipping hot chocolate beneath teepees marked "Troop Beverly Hills."

All of Kardashian's famous sisters -- Khloe, Kourtney, Kylie, and Kendall -- and mom Kris Jenner attended. Other celebrity guests included Serena Williams and models Gigi Hadid and Cara Delevingne. In addition, Kardashian's hubby Kanye West and Caitlyn Jenner were photographed walking into the shower.

The star-studded bash was held at family friends Shelli and Irving Azoff's Beverly Hills home, where the glamorous guests brunched on pancakes, waffles, eggs benedict and omelets, according to E! News. Guests were later sent home with a box of Girl Scout cookies, in keeping with the camp theme.

Kardashian's mom also delivered a sweet speech about how it seemed like yesterday when North West was born.

Kardashian, 35, and West, 37, welcomed their daughter in June 2013, but getting pregnant a second time proved difficult, Kardashian revealed on her series, "Keeping Up With the Kardashians."

In May, she ecstatically revealed on her reality show that the couple were finally expecting.

"I just got the blood test back and I am pregnant!" she announced.

The following month, she revealed that she was expecting a boy.
