Meanwhile, Kim - who also has son Saint, 23 months, and is expecting her third child via a surrogate - previously revealed she dresses her four-year-old daughter in her old clothes.
Kim had the option of telling the truth and revealing all or drinking a sardine smoothie and after the grin had done its job, she opted to chug the smoothie and keep tight lipped, further suggesting there's something to those baby rumours.
The soon-to-be mother of three told host Ellen DeGeneres that her 4-year-old daughter North had taken to calling the unborn child, "Baby Sister". "I'll play with them and just make sure they're okay for Baby Sister'". "We had a baby shower over the weekend and I thought, 'I really do want to have a baby shower, because I want her to feel like something's coming and for her to really understand it, '" Kim explained, referencing her tea-party themed baby shower complete with a cherry-blossom forest on Saturday.More news: Al Franken accuser: 'I've been angry about it ... for over 10 years'
She said, "I'm not gonna name her Star, but my daughter picks that name all the time".
While she mentioned how North is excited to have a sister, she noted that it was a little hard to explain the process to Saint - especially without the belly. "But let's see if it last".

Not a day goes by that we aren't inundated with another story about a mystery baby shower or a loose-fitting top from the half-sisters. Her silence, which means that she doesn't want to and can't confirm the possible good news herself, signifies that something could be true when it comes to those reports regarding Jenner and Khloé, it's just that Kardashian's not going to say anything about it at all.
Corden had to eat some scorpion after declining to reveal the biggest "jerk" he's ever had on the show, while Kim opted to share Kanye West's worst habit to avoid throwing back some bull penis. "It's a different experience". "It's so hard", she said, adding that she and her husband are looking for something "short, easy to spell, one syllable".More news: Australia says yes to same-sex marriage in historic postal survey
