The sisters have had a tough time recently, as Khloe has been dealing with estranged husband Lamar Odom’s health issues after the former NBA star was found unresponsive in a Nevada brothel last month.
Kourtney has been by her sister’s side throughout the ordeal, while also going through a split from longtime love Scott Disick and parenting the couple’s three kids while Disick seeks treatment in a Malibu, California drug and alcohol rehab center.
Khloe, 31, laid low for Halloween this year, telling a fan on Twitter that she spent time with Odom over the holiday weekend, "so he wasn’t alone."
However, spending time with Odom doesn’t mean that Khloe’s relationship with Houston Rockets star James Harden is over. Khloe reportedly called off her impending divorce from Odom so she could have power of attorney for the former NBA star and have authority to make medical decisions on his behalf. A source told ET last week that she and Harden are still going strong.
"They are working on their relationship and are still very much dating," says the source. "This situation is obviously not something they were expecting to happen but James is supporting Khloe through it and they are trying to make it work. They are very much in love."
As for Kourtney, she has continued to support Disick in his rehab stint, even sending the couple’s kids, 5-year-old Mason, 3-year-old Penelope, and 10-month-old Reign, to visit their dad with Kris Jenner last weekend.
"It was Kourtney’s idea," another source told ET of the visit. "Kourtney would never want to keep the kids from their dad. That has always been her #1 rule. She does not want to see Scott at the moment, but she will never keep the kids away from him."
