Kim Kardashian, Kourtney Kardashian and Kris Jenner are back in Los Angeles after spending two days in Las Vegas to support sister Khloé Kardashian while she takes care of her ex Lamar Odom at the hospital.

Khloé remained in Nevada, where she is continuing her vigil over her estranged husband, who sources say is currently on a ventilator after he was found unconscious on Tuesday.

Khloé and Lamar, though separated for years, are still legally married and sources tell PEOPLE she is responsible for making medical decisions for him.

Kim, Kris and Kourtney were spotted driving back into L.A. on Thursday. Soon after, Kourtney posted a poignant photo on Instagram with her young son Reign, 10 months, calling it a “Kisses in bed with my babies kind of morning.”

Kendall Jenner is believed to remain in Las Vegas with her older sister (she cut short a trip to Shanghai, China, for fashion week to be with her family).

Odom, 35, was found unconscious in a Nevada brothel on Tuesday. He was rushed to Sunrise Hospital in Las Vegas, where he remains in a coma.

After learning of Odom’s condition, a source told PEOPLE that Kim and Kris dropped everything to fly to Las Vegas to be with Khloé and Lamar.

The Kardashian-Jenner clan’s apps have been virtually silent following Odom’s hospitalization with Kylie Jenner abruptly ended a live stream being shown through her app and website on Tuesday after the news broke.

A source told PEOPLE that Odom, whose children arrived in Las Vegas on Wednesday, had cocaine and opiates in his system and has had a “couple of strokes” since he was first found unconscious.

The source added: “It’s so sad and the situation is unimaginable. Before Khloé got to the hospital she was inconsolable and now she just wants to be by his side. The Kardashians are his family.”
