Keeping up with the Kardashians reality star Kylie Jenner is keeping her pregnancy a secret. But Breaking Celebrity News has exclusively learned from a family insider that the sad 20-year-old thinks she is as " big as a house" after gaining nearly 60 pounds!

“Kylie's been eating non-stop and has gained a tremendous amount of weight,” the source said. “She is not eating healthy either so it is not making her situation any better.”

Jenner – who is pregnant with her first child from baby daddy rapper, Travis Scott, 25 – has gained almost 60 pounds, the source insisted. “She has a big breakfast, big lunch, big dinner and tons of snacks in between,” the insider said.

“She gorges on food and blames it on being pregnant but says that she is always hungry. Kylie hides her figure in oversized clothes because she does not want to deal with the sight,” the pal added.

“She thinks that she is morbidly obese right now. Although her family tells her that she needs to calm down, she cannot wait to get this baby out so that she can get back to the size she wants to be.”

But it seems there is hope, as Breaking Celebrity News has learned that Jenner is already setting her sights on weight loss post-baby! “After she gives birth in February, she is planning on checking into a fat farm for six weeks. If that doesn’t work, she will resort to using a procedure like lipo or cool sculpting to shed the pounds,” the insider told Breaking Celebrity News.
