Kylie Jenner isn't the only Kar-Jenner sister expecting a child.

Rumor has it Khloe Kardashian is pregnant, too!

Kardashian hasn't really been secretive about wanting multiple children with her longtime boyfriend, Cleveland Cavaliers player Tristan Thompson. It might be safe to say they're getting started after multiple sources told Us Weekly that the reality star is with child.

Interestingly enough, news broke that the youngest Kardashian/Jenner sister, Kylie Jenner, is pregnant too with her boyfriend, Travis Scott's child.

Plus, Kim Kardashian and her husband Kanye West are reportedly expecting their third child after their surrogate became pregnant. Their baby along with Kylie’s is said to be coming in mid-January.

As for Khloe, she’s three months along.

Khloe opened up about having children with Tristan on the 13th season finale of E!’s Keeping Up With The Kardashians.

“He wants to have, like, five or six kids with me, and that’s lovely,” she said. “We could start at one and then grow from there. But now, knowing I’m not on birth control, it’s really scary. It’s like a really big step.”

Khloe hasn’t stopped gushing about Tristan since it came out that they were dating one another.

“I’m in the best relationship I’ve ever been in and it doesn’t take a ring for me to feel that way,” she said in an interview with You magazine as she spoke on rumors that she and Thompson were engaged. “My boyfriend is very protective of me. Feeling loved and validated and secure is a huge thing. Tristan is protective of my entire family, which is beautiful. And I love that everything we do is as a union. When he speaks, it’s ‘us’ and ‘we,’ and that’s important because it shows that you’re sharing life.”

Congrats to Khloe and Thompson!
