The Kardashians have always been a tight unit, and today’s news that Kim Kardashian is filing for divorce from her husband of 72 days, Kris Humphries, is only going to make them stronger. Kim’s sisters Kourtney and Khloé have posted statements on their official websites in support of their sister. Kourtney wrote, “Our sister is going through a difficult time but we’re a close family and are sticking together like always. Kim, we love you. We appreciate everyone’s kindness and support.” And from Khloé: “I just want to thank all of our amazing fans for your unconditional love and support. My sister is going through a very difficult time and your kindness right now means the world to all of us. Kim, we love you more than anything.” On Keeping Up With the Kardashians, the sisters often expressed their concern at Kim’s relationship with Kris, particularly Khloé. Kim and Khloé were expected to arrive in Sydney today to promote their handbag line, but according to reports Kim hadn’t boarded the flight in LA that should’ve brought her to the country today.
