The tears were flowing during Kendall Jenner's trip to the Greek island of Mykonos earlier this spring. While vacationing with her famous family -- including a then-pregnant Kim Kardashian -- the 17-year-old model often felt excluded from group activities. To avoid feeling left out, she decided to spend some time alone in her room. In a sneak peek from the Aug. 4 episode of Keeping Up With the Kardashians, half-sister Khloe Kardashian-Odom pays Jenner a visit to see what's going on.
"Kendall is not at breakfast. Last night she said she felt left behind, and I would never want Kendall to think we didn't want to hang out with her," Kardashian-Odom, 29, says in a video confessional. "If Kendall wanted to hang out with us, the door's open! We're your sisters."
When the former X Factor co-host enters her sister's room, Jenner shouts, "No! Leave, Khloe! Leave! Go away!" Kardashian-Odom persists, telling her sibling, "I want to talk to you."
To find out why Jenner is so upset, watch the clip above and tune in for an all-new episode of E!'s Keeping Up With the Kardashians on Sunday, Aug. 4, at 9 p.m. EST.
