After months of hiding her pregnancy to her fans, "Keeping up with the Kardashians" star Khloe Kardashian is now willing to share some juicy details about her baby bump.

Khloe guested on "Jimmy Kimmel Live!" last Thursday, where she revealed some happenings behind her first pregnancy with boyfriend NBA Star Tristan Thompson. Apparently, she was able to hide the news from her family for a few weeks until she revealed everything.

"First it was Tristan because he kept saying, 'You're pregnant,' and I was like, 'Be quiet I'm not pregnant,'" the "Revenge Body" star said. "I was nauseous, not feeling well and he had to leave the country. I took a pregnancy test and I was screaming. It's so weird and surreal."

"So it was Alexa, my assistant, Tristan and I. We were the only ones that knew for a few weeks until I was able to tell my family," she added. "He was out of the country and we wanted to tell everyone together. It's actually all caught on Keeping Up which I'm excited about. They get to see all the stuff I was going through without them knowing."

Khloe also said that she plans to give birth in Ohio, which is expected since her boyfriend Thompson plays for the Cleveland Cavaliers. When asked by Kimmel who she will bring with her in the delivery room, she said that her mom was on top of her list, and probably one of her sisters who is "least annoying."

Kardashian further told Kimmel that she has been fighting a lot with Kourtney, who is the eldest among the Kardashian siblings. She said that her sister gives a lot of baby advice—which she thinks is very sweet, but pretty annoying at the same time as she said Kourtney mostly wants to get her way.

Khloe doesn't know the gender of their baby just yet, but many are touting that they're having a baby boy. Rumors of her pregnancy have been floating around since the middle of 2017, but the KUWK star only confirmed the rumors with an Instagram post last December.
