Heidi Montag

At just 23 years old in 2010, ‘The Hills’ star underwent 10 body-altering procedures in one day, including a brow lift, a nose job, cheek injections, lip injections, a chin reduction, liposuction, ear-pinning, breast augmentation and a backside augmentation.

At the time, the star told PEOPLE: "I think I look way better and I’m way happier.”

She continued saying that her plan was to keep using surgery to be “as perfect as I can be.”

However, almost a decade later, Montag has changed her mind on the extensive procedures she had done.

She told Cosmopolitan: “I was way too young to make such a life-changing decision.”
