"Khloe is hugely pregnant and is wearing baggy sweatshirts all the time in public, but privately she's super proud of her belly," an insider spilled to RadarOnline.com.
Kardashian, 33, and Tristan Thompson, 26, were expecting their first child together and she made sure her bump was visible for the family's famous holiday shoot.
"Khloe looks great, really happy during her pregnancy," the source squealed, "but Kylie has been totally the opposite."
Jenner, 20, is also expecting her first child , but she wasn't nearly as loud and proud as her big sis.
The family matriarch, Kris Jenner, 62, was micro-managing the pregnancy, reveals the source.
"Kris is orchestrating everything about the pregnancy news, she's a genius when it comes to exploiting everything in the family."
