Bad Influence? Kourtney Kardashian 'Worried' About Scott Disick Hanging With Party Girl Khloe Kardashian

Scott Disick is on the outs with his baby mama while his excessive partying continues, but he's found a sympathetic shoulder close to home — her sister Khloe! Now, insiders tell RadarOnline.com, Disick's longtime girlfriend Kourtney is "worried" about him hanging with the laid-back party girl.

"Kourtney really worries about Scott spending so much time with Khloe because she thinks Khloe is too soft on Scott," the source told Radar.

Khloe's estranged husband Lamar Odom struggled with addiction during his relationship with the youngest of the three Kardashian sisters, and the source said Kourtney doesn't want to be as lenient with Disick's issues.

"Khloe went through a really difficult time with Lamar and so Kourtney is worried that she is going to be way too sympathetic to Scott when he really needs tough love," the source claimed. "Kourtney doesn't want Scott to get away with his bad behavior and she isn't sure Khloe can handle another person with an addiction."

Indeed, on an episode of Kourtney & Khloe Take The Hamptons, Kourtney flipped out on Khloe after she drank in front of Disick during a promotional trip to Las Vegas just weeks after his rehab stay.

According to reports, Disick has been living temporarily at Khloe's pad, where her troubled brother Rob also crashes.
