Kylie Jenner remained tight-lipped on her pregnancy, so much so that some of her family members didn't even know about it - including her half-brother Brody Jenner.
Brody, who starred on MTV show The Hills, revealed toTMZ he had no idea his 20-year-old little sister was pregnant.
"To be honest, I didn't even know she was pregnant for the entire pregnancy," he admitted.
The 34-year-old also said he hadn't seen much of his sister lately, admitting it's actually been a 'couple of years'.
As to why it's been so long since they've seen one another, Brody put it down to both of their hectic schedules.
"The relationship has always been there, they're just busy," he said.
"It is what it is."
Brody is the youngest son of Caitlyn Jenner and Linda Thompson, who was Caitlyn's second wife.
He has featured on the Kardashians' show, Keeping Up With The Kardashians, in the past, with one episode showing Kim trying to explain why she didn't give him a plus-one invitation for her wedding to Kanye West in 2014.
Meanwhile, Kim and Brody's sister, Kylie is now rarely seen in episodes of the show, despite the fact that she starred in her own reality spin-off, called Life of Kylie.
Kylie gave birth to a baby girl, named Stormi Webster, on February 1st, with boyfriend Travis Scott, mum Kris Jenner and pregnant sister Khloe Kardashian by her side.
She took to Instagram on Sunday to share a heartfelt message to her precious bundle of joy and explained why she kept her fans in the dark about her pregnancy.
Acknowledging her secrecy, Kylie said, "I understand you're used to me bringing you along on all my journeys. My pregnancy was one I chose not to do in front of the world."
She added that she 'needed to prepare' herself for the role of being a mother, and so decided to take a step back from the spotlight.
"I knew for myself I needed to prepare for this role of a lifetime in the most positive, stress free, and healthy way I knew how," she wrote.
However, there was so much speculation surrounding Kylie's pregnancy Brody must've suspected something was up. Right?!
Does he live under a rock?
