Khloe Kardashian and sister Kim are now matching blonde babes.

The youngest Kardashian sister showed off her ombre locks while jetting off to Las Vegas from Burbank's Bob Hope Airport on Saturday. Now Kourtney is the odd woman out with her black mane.

During an appearance on Jimmy Kimmel Live on Thursday, Kim revealed that Khloe stopped trying to have a baby with her now-ex-husband Lamar Odom during their marriage.

"For so long, everyone in our family was feeling really sad for Khloe thinking that she wasn't getting pregnant and everyone around her was," Kim told Jimmy. "And the whole time, she wasn't trying to and she was not showing up to these doctors appointments behind our back on purpose."

Khloe filed for divorce in mid December following months of drug use and cheating rumors surrounding Lamar. The couple recently sold their $5.5 million Tarzana mansion.

"She knew it wasn't right and she knew she wasn't ready," Kim continued. "So now we understand it and we understand her decisions, it's very clear."
