The Keeping Up With The Kardashians star, Kourtney Kardashian, is being blamed for her sister Khloe's weight gain. Khloe claimed that she had piled on a few kilos because of 'sympathy' for her pregnant sibling.

Kourtney is expecting her third child currently and Khloe joked that she was now a fuller figure in "sympathy" for her older sister's pregnancy. Khloe has decided to take on an exercise programme to lose the extra kilogrammes, reported Female First.

She posted a selfie on Instagram and a message on Twitter which read:

Monday with @gunnar!!! I am determined to get my pre-hamptons, pre- sympathy kourtney pregnancy weight… http://t.co/fIKbCqKj3I

She blamed her friend, Malika, because she wasn't following her diet properly. On Twitter, she wrote:

I had to do something in the gym today. I ate so poorly yesterday. I blame @forevermalika lol http://t.co/HGsg9mJiEO — Khloé (@khloekardashian) September 14, 2014

While shooting for Kourtney and Khloe Take The Hamptons, she claims that she had gained at least 10 pounds. She took to Twitter to admit this. Her message went like this:

Khloe recently split from her boyfriend French Montana because he had become too "needy." But a source claimed that they were just on a break because their relationship had gotten heavy and so Khloe wanted to step back.

Seems like Khloe has joined her brother, Rob, on a mission to lose weight as he too has piled on a couple of pounds.

Rob is currently aiming to lose 50 pounds. A source told E! News that he hates being fat but has been piling on weight because he is depressed. He is trying to avoid any sort of publicity until he gets healthy. He has moved in with Khloe and now the two of them are trying to lose their extra weight.

An insider claimed that the two of them are motivating each other to work out and stay on the right path.
