With Kris Jenner "coping" with ex Bruce undergoing a sex change, Khloe Kardashian "has been forced to fill in as mother to her younger siblings" Kendall and Kylie.
Insiders tell RadarOnline.com that "Khloe is now mom to those girls now," referring to her 19- and 17-year-old siblings.
"Kris has never been there for them and Khloe is the only one that they can turn to for motherly advice," the insider says. "Kourtney has kids of her own and so does Kim, but Kim is just like Kris.

"She puts her own happiness in front of her parents, and certainly in front of all of her sisters and brothers."
As Radar previously reported, it is not only her younger sisters that Khloe has taken on the parenting role for, but also for her 27-year-old live-in brother, Rob Kardashian.
Last Sunday night, while Kim was with rapper hubby Kanye West at the Grammy Awards, "Khloe took Kendall and Kylie out to have an enjoyable evening away from all the drama," the source tells Radar.
"They did not want to be around Kim because it would mean that they would be stuck in her shadow all night -- those days are over."
