Kourtney Kardashian told boyfriend Scott Disick that she's pregnant with the couple's third child on Sunday's episode of "Keeping Up With The Kardashians," but Disick wasn't too thrilled about the news, Hollywood Life reported.

Disick, 35, had walked in to find Kardashian packing for their two-year-old daughter Penelope when she broke the news.

"How many clothes does one little kid need?" Disick asked.

"A lot. Can you shut the door for a second? I just wanted to tell you that I'm pregnant," Kardashian said with a coy smile, according to The Daily Mail.

Scott was then stunned and at a loss for words.

"You just keep suckering me into these kids. I can't handle all of this responsibility," Disick said.

Kardashian admitted later on that she had trouble finding the strength to tell Disick about their third child.

"I definitely had to build up the courage to tell Scott because he has been just super depressed and I don't want to set him off," she said to the cameras.

She then mentioned that she had suspected she was pregnant since March. Disick said he felt Kourtney was being sneaky and told her that she needs to stop lying to him.

"Just kind of thought that at two we did not want to have any more kids and now I have to look after three. Just saying it is freaking me out," Disick said.

Trying to cope not only with the pregnancy news, but the recent deaths of both of his parents, Disick disappeared following a trip to Mexico. Kardashian said her husband was going out for dinner with a friend after he arrived back in the U.S., but never showed up back at their house.

When he returned the next day, Kardashian told him that it's not okay for him to disappear like that because he has a family. Disick said he felt his behavior was unacceptable, but tried to justify it anyway.

"I definitely feel horrible for putting Kourtney through a rough time when she is pregnant, but I did not want to get back to reality," Disick said.
