Kendall and Kourtney Shut Down Baby Rumors as Ellen Mocks Kardashian Pregnancies for Halloween

Clad in head to toe animal print, a breast plate, fake baby bump and booty and a long blonde wig, DeGeneres' reoccurring character mocked the real reality TV family's many pregnancies by revealing her own.

"I don't know if you remember me, I'm Karla Kardashian. I am the lesser known Kardashian sister and I've got a new baby bump under my lady lumps," she said on today's show. "You know what that means, either I'm pregnant or I put my butt pad on backwards. You watch 'Keeping Up with the Kardashians' right? I'm a big part of the Kardashian family. When the show first started, I had a small part, then I went to see a doctor in Beverly Hills and he made it bigger. That was a joke about breast size."

"This season, all the Kardashians are having babies, or as we like to call them, spinoffs," she joked. "So we all know that Kim is expecting and everyone's talking about Kim and Kylie being pregnant. And I have breaking news and I'm not supposed to tell anybody, but I don't care because I'm part of the family: Kourtney is pregnant as well."

Well, that announcement didn't sit too well with Kourt, who walked out on stage to shut it down. "Stop making up rumors about me, I'm not pregnant."

When "Karla" pivoted and said it was actually Kendall who's also knocked up, the model also surprised the audience to stop the gossip as well. "I'm not pregnant either though. I'm not," she said, "You gotta chill, I'm not pregnant."

Kendall and Kourtney's faux sister also used the opportunity to reveal that her baby-to-be wasn't the only big news she had to share.

"Everybody knows that the family signed a huge deal with E! for $150 million. I haven't gotten my part yet, but I don't care," she exclaimed. "I am the new face for Food 4 Less! Take that! You think of cheap melons, you think of Karla Kardashian."
