If you weren’t already aware of this event from the butt load of Kardashian fam photos, you probably would’ve heard about the incident that involved the local fitness model being carted out of the venue with her face down in a stretcher as onlookers including Caitlyn Jenner watched in horror.

As the shocking photos (you can check them out HERE) went viral online and mass panic spread, Hembrow, 24, decided to take to her popular YouTube channel to address the incident, saying that she’s  “super embarrassed” and blamed the whole thing on a lack of sleep.

“So, firstly I just want to let everyone know that I’m OK,” she said. “Basically, what happened was, I was in L.A. I was running off pretty much 30 hours no sleep. I was struggling to stay awake even when I was getting my hair and makeup done.”

“I was literally sitting there, like, falling asleep. Like, I could barely keep my eyes open. I’ve been throwing myself into work way more than ever, and also, I have my kids the majority of the time. [It’s] literally been like a non-stop, on-the-go kind of thing.”

Hembrow attended the event as she became friends with Kylie’s big sis Khloé Kardashian after modelling for her Good American campaigns.

She went on to also blame the collapse on her current emotional state as she reportedly split from Reece Hawkins (her fiancé and father of her two kids) in June.

“I think because of the breakup I’ve been trying to keep myself busy and not really taking time to think about how I’m actually feeling or focusing on myself,” she continued.

“I probably, definitely shouldn’t have been drinking because of how jet-lagged I was, because of how exhausted I was, and I already wasn’t feeling well at all. I was honestly fine at that point, and I was talking to a bunch of my friends; I was catching up with some people. So, yeah, I pretty much collapsed.”

She concludes the video by asking fans to take what happened to her as a warning.

“Honestly, I’m already super, super embarrassed about it. I read a quote yesterday, and it said, ‘Make time for rest, or your body will force you to slow down in ways you probably won’t like.’ And I feel like that couldn’t be more true.”
