Kim Kardashian recently proved what it’s like to be a trusted sister to her siblings, especially to Khloe Kardashian and Kylie Jenner.

During her recent guesting in “The Late Late Show” hosted by James Corden, Kardashian was asked to answer a series of questions. When she refused to answer a particular question, she would have to gulp down a weird-tasting smoothie.

When Corden asked Kardashian to confirm her sisters’ pregnancies, the soon to be mom of three refused to do so. She ended up drinking a sardine smoothie that obviously did not taste good.

Kardashian isn’t the first member of the Kardashian-Jenner clan that refused to confirm or deny Khloe’s and Kylie’s pregnancies. Last month, matriarch Kris Jenner appeared in the “Ellen Show” and was asked by host Ellen DeGeneres if her two daughters are really expecting their first child.

Jenner refused to give DeGeneres a direct answer so the talk show host assumed that the truth will only come out in the upcoming season of “Keeping Up With the Kardashians.” Jenner hinted on this possibility and gave Jenner a huge smile.

Khloe’s and Kylie’s pregnancies have been reported since September. But until today, they have not both confirmed whether or not they will soon be moms. Last weekend, there were reports claiming that the 20-year-old Jenner already threw a baby shower for her and Travis Scott’s baby girl.

The 33-year-old Khloe is reportedly expecting a baby with her boyfriend, Tristan Thompson. Jenner’s third daughter has not thrown a baby shower, but reports claimed that she will be giving birth sometime early next year. Khloe has also been photographed with her growing baby bump at times, and there have been instances when her pictures did not really prove that she’s expecting.

Meanwhile, Kardashian is expecting her third child, a girl, via surrogate. The “KUWTK” star spilled her baby’s gender during this week’s appearance in the “Ellen Show.” Kardashian also revealed that her 4-year-old daughter, North West, calls her sister, “Baby Sister,” since they have not decided on what to name her.
