Kylie's not the only member of the family keeping the former reality star in her thoughts. Despite some obvious fighting between sister Kim and Rob -- Rob didn't attend her 2014 nuptials to Kanye West, and he took to Instagram to call her "the b**ch from Gone Girl" in March -- she carried a cardboard cutout of Rob's face during her trip to Armenia earlier this month.
"He obviously has some kind of depression," Kim said in a recent intense episode of Keeping Up With the Kardashians. "He is the king of excuses ... I'm the only one that's really tough with him so he probably avoids me the most."
Meanwhile, Kris Jenner has said that if she doesn't do something drastic for her son, "he's gonna die."
"He was always someone who was very athletic growing up, and he's gained over 100 pounds in the last year," she tearfully told a life coach during the episode. "He doesn't want to participate. He doesn't go out of the house. He's missed Christmas, he's missed Kim's wedding."
Whatever his current issues may be, Rob was definitely once close to Kylie. Kylie has modeled for his line Arthur George, and frequently attended events with her big bro. Check out Rob with Kendall and Kylie at KIIS FM's Wango Tango concert in May 2010.
