Kourtney Kardashian didn't bother getting dressed for her latest baby shower. Instead, she wore a pair of plush red pajamas, accessorized with sparkly devil horns.

The pregnant reality star, who is expecting her third child with beau Scott Disick, posted photos from the early morning pajama party at IHOP with some of her closest pals.

"I have the best friends in the world! Sunday morning 9am IHOP in our pajamas! #fancyBabyShower," Kardashian wrote, alongside a snap of her and her girlfriends, also in their sleepwear.

In another photo, she can be seen smiling in front of a white-frosted cake and mug of hot chocolate.

"Baby shower breakfast. #pajamas #ihop #bestfriends," Kardashian, 35, captioned the photo.

The cozy celebration was a far cry from her family-hosted baby shower last week. Sisters Kim and Khloe Kardashian threw a formal Breakfast At Tiffany's themed celebration Nov. 12 at the Montage Hotel and Resorts in Beverly Hills.

"Thank you to @kimkardashian and @khloekardashian for the magical, unforgettable perfectly charming baby shower," Kardashian wrote on Instagram.
