After giving birth to her son, Mason, Kourtney Kardashian has been continually losing weight. Even though Kim is supportive off her sister, saying that:
“My sister weighs less than I do, and she just had a baby—so that’s kind of fascinating to me, she looks amazing.”
However, Khloe, on the other hand, is a bit jealous of her sister’s weight loss. On top o that, she jokes about Kourtney’s weight loss secret: breastfeeding, adding that
“If that’s all it takes, breastfeeding? Then someone breastfeed off of me! I don’t care!”
