Kris is the first famous family member to speak out about the photos of Tammy laying face down on a stretcher, leaving Kylie's 21st bash for the hospital.
Although she wished her well, the momager says she wasn't there when it all happened. "I actually left before any of that happened. I typically go to bed at nine o'clock so it was way past my bedtime," she told Kyle and Jackie O during a radio interview.
After remaining quiet for days, the Instagram model and influencer released a YouTube video explaining the incident, which she blamed on lack of sleep.
“I was struggling to stay awake, even when I was getting my hair and makeup done — I was literally sitting there falling asleep,” she said. “I could barely keep my eyes open.”
Hembrow, who has two kids, said she had been throwing herself into her work “more than ever” in the wake of her split from fiancé Reece Hawkins.
Hembrow, who has modelled for Khloé Kardashian's Good American brand, was amongst a slew of A-listers at Kylie's party including Nicki Minaj, Bella Hadid, The Weeknd and Dave Chapelle.
