Chloe Grace Moretz was told to have some ribs removed to improve her figure.

She said: "I used to get told to change my teeth all the time, because I had a gap, and I was told that to help give me more of a waistline, they could take out some ribs.

"Also, I had some acne when I was younger so there was a lot of pressure to deal with that."

The 'Carrie' actress - who is dating Brooklyn Beckham - admits that she begged her mother to let her have "a boob job, the fat pad beneath my chin removed and a butt reduction" when she was just 16, but she is thankful she was told no.

She told Britain's Glamour magazine: "Luckily my mum and my brothers never let me get caught up in all that...

"If I had done any of those things I wanted to back then, I wouldn't know who I am today.

"Anyway, you shouldn't be allowed to have plastic surgery before you're an adult."

And Chloe feels frustrated that Hollywood seems to increasingly value image over actual talent.

She said: "What is so hard about this industry is that, after a while, the acting becomes a very small part of a very heavily calculated [public] role.

"When what matters most isn't my branding or my looks or my boyfriend, but my acting.

"And if I love a part, I will work my butt off to make sure I get it."

The 'Clouds of Sils Maria' actress takes a sensible approach to her diet and would never "starve" herself with a juice cleanse.

She said: "I can be the best my body can be through training and eating cleanly.

"And that doesn't mean a 500-calorie-a-day diet, by the way, because you shouldn't ever be going beneath 1,200.

"And sure, you can go on a juice cleanse if you want, but be under no illusions; you are starving yourself. That and moving water weight around."
