Khloe joined all of her sisters for Kim's Troop Beverly Hills-themed baby shower on Sunday
She and all four of her sisters wore matching striped pajamas and camped out inside in mini tents for the Troop Beverly Hills-themed shower.
Less than two hours later, the star then left and returned to Cedars-Sinai Medical Center, where she’s been looking after Odom.
Kim, who is expecting her second child with husband Kanye West, initially postponed the baby shower to fly to Nevada to be with Khlo while she supported Odom during his initial days of treatment at the Las Vegas Sunrise Hospital.
“Sister Sunday,” Khlo captioned.
Kylie posted a similar image, and wrote, “Baby shower vibes.”
In another photo, Kourtney and Kylie channeled the Wilderness Girls from the 1989 film with Louis Vuitton suitcases, lanterns, Girl Scout cookies and chilled champagne.
“Just our usual morning routine #troopbeverlyhills #sipstea,” Kylie said.

Earlier this week, Khlo and Odom called off their divorce by asking a Los Angeles judge to dismiss their earlier filing.
“This is a very delicate and difficult time for both Lamar and Khlo , and the most sensible thing to do at such a time is not make any big moves and put everything on hold,” a source tells PEOPLE. “So that s what she is doing.”
