Ah, Instagram: if you believe everything you see, everyone is living their best (and most filtered) life on the social media site – and it can leave us feeling… well, a little insecure about our own ‘imperfect’ existence (both on and offline).

Rosie Huntington-Whiteley’s Instagram feed is, of course, every bit as glossy and envy-inducing as you might expect. But, asked how to snap the ‘perfect’ selfie or photo in a new interview, the model’s answer is refreshingly honest.

“Well, you need half an hour, you need great lighting, and you need to be prepared to take about 100 pictures of yourself, edit through 100 pictures of yourself and then filter them three times,” she tells Glamour.

“You know, come on! Be real! That’s the way it is. I try to be mindful of that when I’m posting pictures, but again, it’s part of what I do and I hope that people don’t feel…that my social media is too obnoxious.”
