"Her body is banging! On that motorcycle, her ta-ta's shaking!” Khloe, 29, said in an interview on Australia's The Fifi and Jules Show.
"Kim's body is so insane… it's a major middle finger to the world and honey, she deserves it!" Khloe gushed.
Khloe also bashed the “disgusting” people who criticized her sister during her pregnancy, when carrying daughter North, now five months.
Said Khloe: "She got pregnant and she got so much scrutiny, and people were just so disgusting to her!
"It's no one else's business… for you to criticize someone when they're pregnant is so disgusting and disturbing to me,” Khloe vented.
