Australian fitness model Tammy Hembrow has opened up about what really happened at Kylie Jenner’s 21st birthday party.
The popular Instagram star, 23, was pictured being stretched into an ambulance at the bash – attended by the entire Kardashian clan including Kim, Kylie, Kendall, Khloe and Kourtney.
Taking to her YouTube channel, the Queenslander – who has, in the past, been named as Khloe Kardashian’s fitness inspiration - told her legion of supporters what had happened to her.
"Firstly I want everyone to know that I'm ok...So yeah I pretty much collapsed. Honestly I'm already like super super embarrassed about it," Tammy said – appearing emotional on the clip.
"I probably, definitely shouldn't have been drinking because of how jet-lagged and exhausted I was and I already wasn't feeling well."
Tammy then went on to give some background details of what caused her collapse.
"So basically what happened was I was in LA I was running off pretty much 30 hours of no sleep," the fitness model revealed.
"I was struggling to stay awake even when I had my hair and makeup done...I could barely keep my eyes open."
The star – who split from boyfriend Reece Hawkins earlier this year – then touched on the break-up.
"I've been throwing myself into work way more than ever and I have my kids majority of the time...literally been non-stop on the job kind of thing," Tammy said.
"I think because of the break-up, I've been trying to keep myself busy and not really taking time to think about how I'm actually feeling."
Back in June, Tammy opened up about her split from Reece Hawkins – explaining the pair had gone through "ups and downs like everybody".
"One or two months ago, I decided to end things with Reece. He didn't cheat on me, I didn't cheat on him. It wasn't like that at all," she said in another YouTube video.
The couple have two children together – Saskia, one, and Wolf, two.
"I don't want people to think we just gave up. Most people know relationships are very complex."
