Kim Kardashian says daughter North West has a "better" relationship with her baby sister than her brother. The 37-year-old "Keeping Up with the Kardashians" star discussed 4-year-old North's dynamic with her siblings, 2-year-old Saint West and 3-month-old Chicago West, on Monday's episode of "The Ellen DeGeneres Show." "She's better," Kardashian said of North's relationship with Chicago. "She's better than she was with Saint." The "Keeping Up with the Kardashians" star said she did witness a "shocking" moment the day prior when North offered Saint some popcorn. "She literally had a can of popcorn and was like, 'Saint, do you want some?'" the television personality recalled. "I was like, 'What?!' You do not understand. She does not share with Saint, she does not hardly talk to Saint," she said. "So that was such a big moment in my household yesterday." Kardashian previously said in a video on her website in October that North was "still jealous" of Saint. "Obviously North loves Saint, she just is still jealous," the star explained. "She needs to still get it together and warm up and be a little nicer, but I think she's getting there," she said. "I saw glimmers of hope a week ago. She's not harmful, she's not hurting him or anything." Kardashian shares her children with husband Kanye West, who posted a cute photo Monday on Twitter of Saint giving Chicago a kiss. "We got love," West captioned the picture.
