In 2009 the 31-year-old hit the headlines when she underwent ten cosmetic procedures in just 24-hours in a very dangerous attempt to change her look.

Without telling her friends or family, and with husband Spencer Pratt‘s support, the reality star had a chin reduction, brow-lifts, ear pinnings, a second nose job and a second boob job and more all in one go.

And now Celebrity Big Brother star Heidi has opened up about how her decision to go under the knife nearly left her dead.

‘Spencer thought he lost me’, she told Paper magazine.

‘I died for a minute. With that much surgery, I had to have 24-hour nurse care and Spencer didn’t want to leave my side. I was at a recovery center and had Demerol to deal with the pain because it was so extreme.’

Explaining the moment her former co-star and husband Spencer was told about the complications of her surgery, Heidi continued: ‘My security guards called Spencer and told him, “Heidi’s heart stopped. She’s not going to make it.”

‘And I easily could’ve. Cutting yourself up isn’t something I’d recommend, and Demerol isn’t anything to play around with. That’s how Michael Jackson died.’

Although she admitted to regretting her decision to have so many procedures, the telly star has said that the terrifying experience made her realise what was important in life.

‘I had to look at myself in the mirror every day healing, and be like, ‘What did I do to myself? How did I get here? What is going on? But a lot of positive things came out of that.

‘I basically had to hit that rock-bottom moment in my life, to realise what was important to me’.
