After their nine year relationship Kourtney Kardashian and Scott Disick have called it quits, and Kourtney’s sister Khloe is showing her support on social media.

31-year-old Khloe took to Twitter and posted “Everyone has their own journey to the pursuit of happiness,” which seems to be aimed towards her sister. Khloe is the first from the Kardashian Klan to publicly show support for her older sister after news of the split broke earlier this week.

Disick and Kardashian ended their relationship after photos surfaced of Disick partying in the South of France with stylist Chloe Bartoli, and this is not the first time that the two have been linked together.

Kourtney and Scott have not yet spoken about their breakup, but a source told PEOPLE Magazine, “Kourtney is willing to sacrifice her relationship with Scott in order to keep [her kids] safe. [Kourtney’s] children are her first priority. She needs to protect herself and her family, so she knows this is the right decision.”
