The Jenner girls visited Harry, who has Hodgkin's lymphoma, in the hospital and shared photos of themselves striking yoga poses with their friend on his hospital bed.
"So blessed to have friends like @KylieJenner and @KendallJenner who haven't left my side during this tough time. #fam," the 20-year-old Tweeted about the girls.
Harry, who's also a recording artist and friends with Cody Simpson, has undergone chemotherapy treatments more than 10 times to try and beat his cancer. Kylie also visited him in hospital on Nov. 5 as he went through another chemo round.
We think it's great the Jenner sisters are so supportive of their friend and that Harry gets well very soon!
