Scott Disick and Kourtney Kardashian Scott Disick and Kourtney Kardashian

Another Kardashian is headed to splitsville: Kourtney and Scott Disick have ended their relationship after nine years, E! reports. While the pair have yet to comment, Kourtney, 36, reportedly dumped her on-again, off-again boyfriend after he was seen getting close with an ex-girlfriend in Monte Carlo over the weekend. (You can see those pictures here.)

Although the couple's issues have been detailed on their numerous reality shows, they seemed to have had a united front until recently. Just a few months ago, when Disick, 32, entered rehab for his addiction struggles, Kardashian told E! News, "He's doing well, and you know, focusing on himself and working on himself. He's made a lot of progress, so I'm proud of him."
