The 17-year-old reality star has assured fans of the Kardashian/Jenner clan her older half-sibling Kourtney, 36, is staying strong following the end of her nine-year relationship from Scott, 32, this week and has had the full support of all her sisters.
Speaking to E!, Kylie revealed: ''Kourt is actually doing great ... Everyone's doing good. I'm doing good. We're sisters. We always stick together.''
Kourtney - who has three children, Mason, five, Penelope, three, and six-month-old Reign, with Scott - has sought comfort in her sisters Kim Kardashian West, 34, and Khloé Kardashian, 30, since the break-up and the trio were spotted out for dinner earlier this week and out at Malibu Wine Safari on Friday (10.07.15).
Although neither Kylie or Kendall Jenner, 19, were at the meal they have been constant contact with their big sis.
Kylie added: ''It was an older sister night ... but we've been talking. She's been helping me with my house a lot.''
